I mean traits do play a big part in the idea that the character type is constantly reused. It's like a checklist for "crazy for murder" character. Weird crazy smiley face while talking about killing? Check. Hyper aggressive and impatient? Check. Overconfident in their ability to kill...
I wish they came up with more interesting personalities for bad guys. We've got the clearly more powerful leader guy. We've got the quiet and controlled guy. And we've got the ever boring "I'm CRAZY for MURDER" guy.
