I fantasize doing this to people's penises

Well one day I came across someone's photo of his penis. It was semi-erect and it looked like I could grab it. Then all of a sudden I got this idea, to grab the guy's penis, take a machete and hack it off in one blow. Then I imagine the blood spilling out of the severed penis and watching the erect balloon turn into a piece of flappy skin. Yes, I sometimes fantasize about grabbing people's dicks and hacking them off with machetes. No I am not trolling, but don't worry I won't do this. It is just something I think about to amuse myself. There's something funny about taking someone's semi-erect penis and swiftly hacking it off to me.
Is this normal?
