Mine would be sending Bryan Wilks to Paradise Falls in FO3, I mean he just lost his father. Then he puts his trusts in this stranger who's willing to help him, and end up being a slave.

Killing any good old npc like old lady Gibson by accidental shooting

In one playthrough of Fallout NV i killed Mr.House.

Killing ED-E in the Divide to launch the nukes, i don't know if that's just a bad Karma choice but its literary the only one that made me feel somewhat sad.

While doing an evil play through just to see what it was like, I made it possible for Bumble to get kidnapped from Little Lamplight.

I learned my lesson when Tali killed herself in ME3. I save my games very frequently so shit like that doesn't happen anymore.

I also did that, these Paradise Falls quests are pretty dark.

I once stole a cup by accident in Moriarty's Saloon in Megaton and the whole town attacked me... I only cried for 30 minutes.

Well even if I had Very Good karma that choice made me feel like an asshole.
Sacrificing ED-E was sad but it's for greater good.I suppose.
I didn't want to nuke already irradiated mojave :/

I didn't care that I shot up little lamplight. I felt bad killing all the dogs there. I love dogs way too much.

In the many times I have played through New Vegas, once and only once did I decide to join the Legion (For the achievement and nothing more). I committed plenty of atrocities, but my worse was selling Arcade Gannon, my favorite companion, into slavery to help save the life of the madman once known as Edward Sallow. And in the end, Arcade's sacrifice resulted in him being a sad causality of the war, to be heaped into an unnamed canyon like so many others. As I listened to this while the end slideshow music played (https://www.youtube.com/watch?v=730jXH_Ni7Y&index=70&list=LLGRd4LTg0ujyWpE4xzcR_4A), I could not help but cry at the end of my best friend's unfinished life. Because war... well, you know the rest.

RIP Arcade Isreal Gannon. You will not be forgotten.

I felt bad when I set off the nuke in Megaton I was thinking of doing a bad Karma play through so I set the nuke off and instantly felt bad so I turned and shot Mr. Tenpenny in the face and throw him off the tower to make myself feel better it didn't really work so I loaded back and disabled the nuke then went back to the tower and killed Mr. Tenpenny then I felt a little better.

I wasted Three Dog (Awooooooo!) while he was sleeping to avoid his separate quest. Oops LOL

Destroy the very last essence of America AKA killing the NCR, Enclave, Brotherhood (somewhat), and all other American influenced faction (I was playing as a man who was brainwashed to destroy all the very last essence of America) ENDING DEMOCRACY!!!!

I was taking a screenshot in doc Mitchells home with tfc enabled and aimed my gun and shot as I wanted to get a picture as my gun shot I thought it was a Lil weird I heard the bad karma sound so after 5 minutes of taking the right picture I pressed tfc to resume playing and noticed a bloody mess in the corner of the room I accidentally shot doc Mitchell at point blank with a catalyst shotgun I put my gun away and slowly snuck out of town lol

Ahh I got one this one is terrible and could effects the wasteland greatly in theory plus he is a cool guy I wish they would have went some were with him. Killing Harold the tree man. not only are you crushing the tree minders hope and dreams but also the possibility of life being better, greener if you will

Working for the Van Graff, I made a terrible mistake by bringing them Cass... Never working for them again.

Heh...I almost always kill Mr.House xP I regret killing/betraying Ringo at the start though...I've only done that once and I won't do it again

I felt really bad when I killed the Think Tank. So bad that I went back and forced my stats so I could beat their conversation checks without fighting again.

In Infamous when I saved Trish instead of a bunch of other people. Plus it turns out it wasn't her I was saving it was some random woman and she was with the other group.
