Is it wrong that gory films make me laugh?

Sounds like a perfectly natural reaction to gore. That's how your mind deals with it. You're certainly not the only one who has the same reaction. And when it's real, it also sounds like a normal reaction. Anybody who isn't reviled by real life horror should probably not be walking around in public!..Btw, I like my own blood too, but I prefer to keep it inside me! Sounds like you now may feel the same. :) Hope this helps!...Cheers!
