Now I’m my opinion Jeff the killer had the WORST character build-
Originally, just your average run-of-the-mill kind of guy, Jeff's life turned upside down after becoming severely disfigured, which emotionally scarred him.
Now don’t get me wrong, I like Jeff’s character itself but just not the background he just had a bad build as a proxy compared to any other one, in my opinion and HOW I WOULD WRITE IT would be different but I won’t say my background made by me because I don’t wanna mix the real story with mine but personally his background could have been better
