I wrote credit card software for a major bank... yeah, actually if you've applied for a credit card online you very well may have used it. I quit it was so evil:(

Not an entry, btw, just a reply.

The most evilest (and meanest) thing I have done begins at about 6th grade.
There was this boy, for whatever reason was always around me. Not sure if he had the hots for me or not, but I wasn't having it. I used to kick him in the nuts most of the 6th grade school year. I have no idea what possessed me to kick him in the nuts a lot, but it was mean and evil now that I look back on it. He moved away the following school year, I think.

When I was 8-9, I whiped a dragonfly's tail off with silver chain(like Geralt used in TW1 cutscene) when it was flying. I don't know why I did it that day but it felt pretty good.

No, it makes me sad, but I did it.
Dude died like 5 years after it happened, and I still feel bad thinking that it might have something to do with the leg breakage. Or not, but still feels horrible.

I borrow a copy of Sims 3 just to kill sims.

created a large Family 8 people, Used Money Trainer then built a Walled pool then sent them all swimming deleted ladder, completed wall then increased game speed and laughed as they drowned.

Goes off to make new Sim Family to die in a fire

Every normal country. In Poland Police is only after pimps.

Many years ago I was temping at a large computer firm in the UK. One day they decided to terminate my contract due to someone else's fuck up while that person had their contract extended. That pissed me off enough that I deleted a few key system files from the Window's folder on all the PCs in that office.

The beauty of Windows back then was that you could happily delete those few files while the system was running and it wouldn't be a problem until the next time Windows attempted to reboot.

A friend of mine who worked in their tech support section said it took the better part of a couple of days to get their systems back online as for a long time they were complete clueless as to the cause ;)

Once, I shot a man in Reno, just to watch him die.

My friend stucked in "Amnesia: The Dark Descent" so i gave him tip to go to a place where i knowed that there is a monster...

Well, let's see...

1) Every single person i met will die in the next 100 years. It can be the next day, 27 years later or 99 years and 364 days. But no one will live more than 100 years after i met them. Every-single-person. No matter their gender, skin color, IQ, favourite game... They are doomed. So, i probably killed more that thousand of them, some of them is still alive, the most are not.
And they don't even know it.

2) Long ago, at winter i tricked my little brother. It was night, it was cold and dark. He wore pijamas, and i send him to the garden, under a big tree. It was a very old tree with a lot of branches - and on every branch there was a nice pile a snow. I used my superhuman marksman skill to throw a snowball to the branch he stood under. After it he nearly looked like a snowman. Muahahahahahahhahahahahahahahahhahahahahaha //yes, this is an evil laught. I just wrote it down because if i send you the mp3 you will think i'm mad.

2 funny things: First, after my legendary shot with the snowball i lost my sklls - since then totally miss the trash can every time i try to throw something out no matter how far away i am from it. Second, after doing my fearsome evil laught for some time i start to laught on the way i laught before... So, it's like an infinite laught circle, but luckily it's not infinite.

You are the worst person than I am.

When I was very young, my ex-girlfriend had cheated on me with my close friend. I was very enraged about it so I decided that I'd do something on my last day before I move back home.

On last day, I drank about 5-6 water bottles then I emptied my entire bladder on her front door. I made sure that my urine soak into the carpet very very very well. Took me few minutes to complete whole operation.

All in ninja outfit so no one will recognize me.

Few hours later, I was on plane and no one know about it. :D

I obey the speed limits and I'm proud of it. That's evil, right?

I'm really sorry to hear that. Forgive me.

Relax. That was a line from Johnny Cash at Folsom Prison.
