Is it normal that i have an urge to kill?

Well, I really don't like to talk about this, and the only person I did tell said he was uncomfortable and called me a "fucking psycho".
But I really just want to stab someone until they bleed to death and watch them die and let their guts slip through my fingers. I occasionally look up car crash accident images on google for fun. It would turn me on, when I see dead bodies, (mammals, not including birds). I get really excited to the point that I start to shake and I can feel my heart racing in my ears. The smell of rotting bodies doesn't phase me. I was standing by a slaughter house in front of horse and cow skins covered with lye and a small lake filled with intestine and blood that was burnt and rotting, also I was standing next to our pet dog named Lexi that we thought was missing for about 7 days but she was rotting in our backyard and It didn't bother me at all, I was even eating the cashew chicken special from Hong Kong inn, It's a great place really, cashew chicken is one of my favorite foods next to chicken dumplings. I'm also curious what humans taste like, I love to cook. One of my favorite things to make are cordon bleus. I like ramen noodles too. I eat a lot of eggs, I'm 5 ft and 89 pounds so i'm trying to get taller. (that's possible, right?)
