Then I guess the "good guy" in your world is only a seemingly good guy (as PG may state it) in my world, since it would be at the core of my definition of a good guy to be fair even in a "you vs. them" situation.

It is rarely as easy as that. How about feeding your family involving you screwing me over vs feeding my family involving nobody screwing anyone?
