Is it normal to get turned on by evil stuff as a kid?

I can't relate with you on the killing animals part, though.

I had a thing for villians as a kid. As I grew up, it ended up turning into full blown fetish.

I wonder if your attraction has more to do with one person forcing another to do something that he/she really doesn't want to do. More of a
control/submissive type of thing?

I too was raised in a very strict religious household. but  I sometimes wonder if my parents teachings somehow back fired on  me. I've always been drawn to villains and what they represent. i always wanted to see darkness and evil prevail. I don't think I  was ever necessarily sexually turned on by this as a child. but now that I'm older, I definitely find it  more and more exciting.  it's expanded to not just villains, but things that are macabre or very dark in nature. for example I watched this show last week called an american horror story which is pretty disturbing and sadistic. the religious side of me knows I shouldn't watch it, but the other side finds the darkness so enticing and even arousing in a sense. I know how you feel, I'm considered the nice sweet good one amongst my friends. but I have this other side buried within me. however i don't really feel sick, or guilty. I've never acted on these feelings; I don't practice witchcraft or voodoo or Satan worship or anything. It's not like I asked to have these feelings; it's just the way it is.

Isn't it interesting how we can have these ideas and thoughts that are some how implanted in us at such a young age? and like you said, sometimes we're even too young to fully comprehend what they mean. I always think about stuff like that. where did it come from? genetics? something to do with how our family raised us?

Don't worry too much about it. Most kids like to experiment with cruelty.

When I was 7 I threw my cat in a drainpipe. I think she died in there, because she never came home. It gave me a thrill that I didn't recognize as sexual until a few years later. I felt terribly guilty after that, and was terrified that my parents would find out what I'd done.
Then my dad took me hunting when I was 13. I had this deep thrill again when we were in the woods stalking deer, and I was nervous. I was terrified that my dad would see how aroused I was and think I was weird. We didn't find any deer the first day, but I was so turned on that I snuck out of the cabin at night with my rifle and hid behind a tree and put the rifle on the ground in front of me and just stared at it while masturbating.
The next day we found some deer, and I shot one. I was so nervous that I hit it low on the flank and wounded it, so we tracked and found it had died about a mile away.
Then the strangest thing happened. My dad congratulated me on my first kill, and suddenly the thrill just went away. I didn't even feel like I'd killed anything. I soon realized that the fear of being caught was a bigger turn on than the killing itself.
A few months later I was walking through town when I saw a stray dog. Suddenly I couldn't control the urge, so I followed it behind an old shed and killed it with my pocket knife. I masturbated right there over the corpse, and had the biggest orgasm of my life. After that I killed more dogs and cats, and when I was 17 I killed a horse. I killed my first hooker when I was 19. I still think the fear of being caught is my biggest motivator, because every time i see "Serial Killer Still At Large" in the papers, I get immensely turned on.
