Is it normal to have these interests

Is it normal that I am leaning towards Satanism?

I grew up (and still growing up) in a religious household. I never felt like I could believe in what I wanted, even though my mom would say "believe in whatever you feel is right" (but I was never allowed to play an ouija board, or speak about psychic's or playing cards)
I always felt trapped, and I am sure that's normal for most people out there.

FEW months ago I got into true crime. Like not on tv or anything, like scrolling forever and ever on my tumblr feed about TJ Lane, Eric Harris & Dylan Klebold, Dylan Roof and other murderers, looking at pictures, gifs and videos/home videos, documentaries of it. Eventually got to the point I would look at that stuff every single day.

Now, I don't even need to ask (is that normal) because obviously its fucking not, I am 100% sure I am going insane. I would just like your input on it.
However
I am now leaning towards to "fucking satan"
or
"satan banging me"
that is now my new fetish. Turning the lights off and imagining Satan sticking his long fat cock in my tight pussy.
Now, lets just say i didnt know if it was normal or not, atleast for someone my age. Which, that is 17.
Put your input on this ;)
