I used to have some serious guilt about this sort of thing, but not anymore. I was in therapy for a few years, and it sorta worked. I don't even feel bad for wishing horrible things on others; as long as I don't harm anyone unnecessarily, I've nothing to feel guilty about.

Part of what helps me is that I know that I have extremely strong self-control. I've had strong homicidal urges for years and years, but I don't hurt anyone. I've also got too much empathy to properly qualify as a psychopath, even though I do exhibit some psychopathic tendencies.

Hell, I've been morbidly fascinated since I was in elementary school. This is part of who I am, but it's not all that defines me. I want to do terrible things to people, especially the ones I love most. However, I'm not hurting anyone unless they pose a direct threat to me or my family.
