If you believe in the butterfly effect, you know that even the tiniest action can cause an avalanche of bad outcomes in the long run. Sometimes, that action is intended; other times, it's something completely accidental.
Just think of the discovery of penicillin: microbiologist Alexander Fleming found the Penicillium mold in his petri dish after coming back from a vacation – he had no intention of discovering antibiotics.
But sometimes, the accidental action has the potential to ruin someone's life. That's what we discovered when we looked at some Reddit threads where netizens asked, "Have you ever unintentionally messed up someone's life? How?"
From lost college scholarships to exposed secret affairs, these people were the unintentional catalysts for some dramatic incidents!

Freshman year of college, week 2. Playing touch football in the quad with randoms. Go up for the same pass as some guy. I catch the ball because I can jump higher. Down he goes. Down i come on top of him. ::CRACK:: Compound fracture to tibia. Everyone screams, he's in shock, I'm in shock picking the dirt off his protruding bone. Ambulance arrives, takes him away. Weeks later he comes back to clear out his dorm room. Turns out he was in school on a track scholarship and without that leg he couldn't run. Without running, he couldn't keep the scholarship. Without the scholarship, his family couldn't afford to send him to school. He will never run competitively again. My bad.

I came into a woman's life she had a great career and prospects but I was so demanding she spent all her time on me. Years later she's struggling to find a footing in a career and a social circle of her own.
Sorry, mum.

Being in the US military, committing adultery is taken pretty serious. A "friend" of mine told me she was hooking up with her married superior. (I say "friend", because no real friend would have put me in that situation.) I got asked about it by someone higher up and I wasn't about to ruin my career by lying, so I told the truth. A lot of people took her side. They both lost rank. He got kicked out. His wife left him. Last I heard they were married. They deserve each other.

When I was in highschool I was studying Blood types and how traits get passed on from parents to children.

I started asking my family members what their blood types were in order for me to make a chart for Dominant and Recessive traits.

Well I got to my Aunt and uncle who were both O positive and after some research determined that none of their kids were fathered by my uncle because they had completely different blood types.

She confessed that she cheated on him 20 years earlier and continued the affair for 9yrs. Uncle was devastated and kids were wrecked. They got divorced, my aunt moved to Alabama to live with her long time BF, my cousins got all [messed up] and one moved in with her own BF and got pregnant.

TL;DR: Studied blood types in high school. Revealed my cousins did not belong to my uncle. My aunt cheated and lied for 20 years.

My best friend when I was younger was an incredibly fast sprinter. His dream was to represent our country in the Olympics. He very easily could have done that, had it not been for me.

We were out one day playing in the forest (we were about 12 or 13 at the time). We saw a little stream and thought how cool it would be if we jumped across it. We did a few times and it was awesome. We did it one more time and I bumped into him in mid air. He landed awkwardly and broke both his legs. Bones were sticking out. It was horrific. I ran to get his mother and he was taken away in an ambulance. He had several surgeries and months of physical therapy. He never ran again and we lost contact.

I blamed myself for years and watched the Olympics last year and felt angry that he wasn't there, when he should have been. I bumped into him recently and drunkenly apologised for ruining his chances at being an athlete. He laughed, called me an idiot for blaming myself for so long, we had a few drinks and [slept together]. So it all worked out.

Hit a car in the rain. Everyone (little girl, boy, mother, and dog) was fine but the weird thing was that the car was full of clothes and seemingly random items. I distinctly remember a blender. And they were all dressed in there pajamas as though they'd just hopped out of bed, loaded up the car, and set out. Well, eventually the father shows up. I'm standing next to the little boy, he's probably twelve, while all the cops, firemen, and on lookers are hurrying around us. It is absolutely pouring. The father sees the kid and walks straight passed him to go look at the car. It didn't hit me until later that they were running from him, but I knew something was off. I looked at the kid and said I was sorry and that I couldn't see through the rain. He didn't even look back. He just stood there staring straight ahead in his soaked clothes with that angry look kids get when they're trying not to cry. I knew he hated me and I knew I had just put the cherry on top of a horrible childhood.

I will never forget that moment. They never filed an insurance claim and I never saw them again. I destroyed someone's life and all I had to pay for was a new bumper and grill for my truck.

In high school my then boyfriend broke up with me. One morning I noticed him showing our mutual friends a coke bottle. I asked a friend later what was in the bottle. It was gasoline. GASOLINE! He brought it to school to get high.

I ended up turning him in to campus police and he ended up going into a mental institution and expelled from school. He's still pretty messed up, arrests for trapping and such. Good times.

When I was 6 my sister and I were skipping rocks. I tried to pick a big one up and lift it behind my head to throw it. As my arms swung backwards, the rock slipped from my fingers and hit my sister in the back of the head.

6 months later she started having seizures. She still gets them 21 years later. I can't help but think it's my fault she's epileptic.

Caught a dude for massive theft at my business. He came into my office, and begged me not to go to the police because that would mean the end of his marriage. So we signed an agreement where in lieu of criminal complaint he would return what money he had left (he blew about half of it on stupid [stuff] already) and admitted to the theft in writing. So he makes payments on the agreement, and like a [jerk] he is, stops once the statute of limitations for criminal complaint has passed. Which is really odd, because he already paid back about 85% of the money stipulated in the agreement. I'm pretty sure he got some bad legal advice somewhere. So we file a civil suit against him for the entire amount of theft plus a massive penalty plus our court costs as laid out in the agreement, he spends roughly $30K defending against the suit, his wife finds out about it, and now it's on his record for 20 years because we win and he owes us more money than he will ever see again in his life. The really stupid thing is that if he paid us the money he spent on defending the suit, he would have paid off the agreement.

We had an employee whose entire job was to manage this spreadsheet. To help her out, I wrote a massive Excel macro that did her 8 hours of work in 30 seconds.

Instead of finding something for her to do, the boss fired her and I got employee of the month honors and a $750 award for saving the company money by eliminating her position.

Edit: By "entire job", I mean everyday. I replaced all of her responsibilities in totality with an Excel macro. She was replaced with a ctrl-G.

When I was a freshman in high school (14 years old), my friend told me how she had been sleeping with her best friend's dad for over a year.

I don't do well with big secrets on my conscience, so I broke down after marching band one night. I told one of my friends who made me tell our band teacher, who reported it to the police and talked to my friend's parents.

She told her parents I was lying about it, but that Monday morning I was called to the principal's office where I had to tell the band teacher, principal, and the police.

Later that week, the news reported that the man was arrested. I don't really know what happened after that, but it's safe to assume that I probably ruined his life and he doesn't even know who I am.

I started a butterfly effect that got one of my highschool teachers fired and blacklisted in the state. He was trying to get the theatre teacher fired behind her back and sketchy around female students, one day he called me out for waiting to use a saw for Stagecraft, and I blew up on him, called him every name in the book and essentially told him he was a [horrible] person for reasons X, Y, and Z. I got sent to the office but since my record was spotless they just sent me back to class and had a meeting with the teacher. Eventually a lot of other students got the courage to call him out too.

The next year I graduated and I heard that he was harassing a female student and the entire class he was teaching reported it. He got fired within that week. It feels good to win.


I also slashed his tires.

Edit: His wife also left him after he got fired.

Right after college, I worked in a copy/shipping/print shop. (Like a FedEx store with more services, basically.) The day before Valentine's Day, this college-age guy comes in and says he wants to get something laminated. It was a Transformers Valentine's Day card he made for his girlfriend when they were in grade-school together, which he recently found and now wants to give it to her a second time, years later.

Pretty sweet, right?

I'm in the middle of a large print job, so I tell the guy it'll be around 30min before I can get to it. He pays, gives the card to me, and leaves. I finish my current job and go to laminate the card. I put the card in the plastic sleeve and between some heavy cardstock, feed it into the machine's rollers... and the machine eats it. It gets caught between the rollers and the machine starts twisting and ripping it all up, melting the plastic together and crushing the card. I try to reverse the machine and get it out, but it's jammed in there really good. I wound up having to actually take the machine apart to get it out.

The card was utterly trashed. Singed, crumpled, ripped, and sealed in lumpy melted plastic. When I told the guy and showed him what was left of the card, I felt like I was kicking a puppy. He just had the saddest, most helpless expression on his face.

I managed to extract the remnants of the card from the plastic and scanned it all in, then spent the next two hours doing my best with Photoshop to fix all the damaged spots and creases, then printed it out on cardstock and laminated that. It actually looked pretty good when I was done, but... I know it wasn't the same. Ugh, I feel bad just thinking about it. That poor guy.

I introduced my friend to both World of Warcraft and League of Legends. He used to be an aerospace engineering student. Now he's taking one class at a community college.

Crashed a car with my girlfriend at the time in the passenger seat and broke her back, shattered some bones in her hands, and put a gash on one side of her mouth ruining her smile. She was likely destined for Cambridge or Oxford, was an excellent piano player and had everything her somewhat meagre upbringing could afford her to get her where she was likely going. Incredibly talented intelligent and fairly pretty young girl. Once she was out of resting and back to school she became lazy and unmotivated, was kicked out of the private school she had a scholarship to, her damaged hands meant she couldn't play anywhere near the level she used to be able to and the big scar on her cheek made her feel ugly and she let go of her body. We parted ways fairly amicably, but later she came to resent me for the issues the crash caused the rest of her life. Last I heard she was at a local community college studying photography, where she apparently had fallen in with the wrong crowd and wasn't doing too well.

I'd love to go back in time and brake a few metres earlier, or at least message her and tell her how sorry I really am, but I know I should leave it in the past.

The crash changed my life as well, I had recently passed my PPL and was enjoying that, I picked an illness up in hospital which kept me from flying for about a month. I was then meant to go onto commercial training, but in the time I was in hospital, financial ruination of my father meant that was no longer possible, so I went to college to study aeronautical engineering, which I wasted, went into a retail job where I still am, and that's the story of my last 6 years.

This went a bit of course and for that I apologise.

I introduced a friend of mine to World of Warcraft while he was in college. He was graduate biochem student and had an internship in a lab somewhere. From what I could tell, he was on his way to a pretty good career.

Now he lives in his mom's basement and has no job.

But he does still have a WoW account.

So he's got that going for him, which is nice.

I mean, I kinda just set it up so that they would do it to themselves. I was getting ready to move out of an apartment where I had threr roommates and a couch guy. I had renewed my lease, but the couch guy offered to do it for me, the roommate that was letting him stay there was leaving so he'd need to find somewhere to live.

He had been dragging his feet on getting his end of the paperwork done, like, stuff that took 10 minutes and that I had printed for him. One day, as I'm getting ready to leave, he tells me that he went to the leasing office and finished his paperwork and they told him that I should just give him my key. No reason to drop it off at the office. Which struck me as weird. I went by the office to talk to them about this and make sure it was on the level, which of course it wasn't.

The leasing office people tell me that he never dropped off any paperwork and that you would never, *ever* just give your key to someone else. So, his stupid little plan became clear to me. What he wanted to do was just take the key and live in the room while I was responsible for every payment until the lease expired. I was kinda furious, so I told them to put the room on the public waitlist in two days, turned in my key, and left.

I shot him a text that he needed to get his paperwork in, outright ignoring the lie, but also not letting him know that the room would go to the first in line in the next two days. I left him with the impression that his little scheme was still going according to plan. Things would only go wrong for him if he went forward with it. Which he did. The room was filled by someone on the waitlist by the end of the week, and I didn't pay a dime in additional rent. He was kicked out and Portland's newest homeless youth. He sent a pretty long, angry, and rambling text to me sometime later, which I just ignored. I'm pleased with my work.

According to my ex I ruined his life. He quit his job to "take care of me" (I in no way needed taking care of. It made life a little easier for me but I could have managed on my own). I was dealing with low level disability onset and he was basically driving me to work and doctors appointments. When he wasn't driving me around he was playing games or sleeping around though. Eventually when he decided to go back to work the only place that would take him is Walmart, right before I left him. He has convinced himself and several other people that I'm the reason he's stuck at such a low end job while I have a manager position in tech that I in no way worked for.

I used to be a nanny and one night my one kid was not listening to me what so ever. He was playing video games and I had given him multiple warnings. (Thirty minuets until dinner, Fifteen, ten etc.) It was usually understood that he needed to finish a game and then be at the table when it was ready. I would never make him get off without many time warnings and if he was in the middle of something and would be a few minuets that wasn't a problem. I told him dinner was ready, his siblings were already sitting at the table and he started another game while I was behind him and said he had been in one for a while. He was on my last nerve so I turned off the router. He threw a fit and screamed that I had ruined his entire life then cried for half an hour. This was five years ago and needless to say his life is fine. He no longer throws fits and we are pretty close.
