Hmmm, now you mention it, I don't think I've ever actually seriously injured someone in an 'evil' way. I've had dreams where my intention has become evil, or I turn evil, but never actually get around to hurting anyone.

Once a shot someone (with a paper gun). I was kinda evil at the time, but then he didn't die, I felt bad and it became more of a nightmare. I tried to kill him quickly. He wouldn't die, instead he just sat there and whined about his pain. :\

It was a bit wierd, but whatever. ^^
