I also think good is relative, by "good" I ment "good in this case from my point of view" - survival of the Swan song crew...
(Now I think I am little bit like Pi - I know the crew, enjoy their escapades and not really care about other people that may die on the way... Well I care a little. But not much.)
On the question of "are we good/bad" - if it is like you say and we bend everything to survive, the final judgement depends on what you think of survival. I think that most people would say survival is good, but there are good and bad ways to go about it.
Anyway I don't think it helps so much to judge if something is good or bad, what seems to be important is to find ways how to resolve conflicts so that everyone gets what they want and don't carry on pain that creates more pain elsewhere.
