Y, "where does guilt fit in?"

You have been given some good replies.

When speaking of evolution I can not equate things like love, happiness or guilt to any thing related to evolution. I see people with a main board that was provided by evolution. It had some basics like how to walk and eat and do the obvious things nature will mandate. We, us and others like us, created emotions like programs that made the basic machine human.
Just a thought.
