Is it normal to have horrid thoughts of torture and murder?

I like to fantasize about placing some of the people I know in horrible, gut-wrenching and traumatic situations and experiences and think about the absolute pain, fear and anger in their eyes as it all plays out. Not because I am mad at them, no. I'll fantasy-torture myself the people I hate in the most creative of ways. I'm that kind of person who watches deaths and gore complication videos on youtube. Maybe it's worth mentioning that I drew pictures like someone cutting off someones fingers with scissors and killing bugs and other small animals as a child. I don't feel guilty about any of this. What do you guys think?
