Well i'm certain that what makes a specific individual feel guilty will be based on societal factors, but the actual chemistry of guilt in the brain will be totally seperate to that. I think it is this aspect that the OP was getting at, then once the feeling is in place in the brain it can then be utilised by the society.
That does not follow, as far as I can see. What wrong with an adaptation that specifically facilitates pack behaviour? I don't see any reason to speculativiely nominate some other influence.
