Don’t you blame the movies! Movies don’t create psychos. Movies make psychos more creative!
I really believe that this isn’t a remake and Ash is just a bimbo and dealt with his trauma from the first movie by getting a gf with the same name as his dead one, buying her the same necklace, and then going to a cabin in the woods to try to replace the bad memories of all his friends being possessed and dying. Why did he play the tape again? He is simply too pretty to also be smart.
