It's because we're all bastards.

Is it based on scientific research? Or just your personal experience?

It's actually consistent with my observation that all living things are necessarily selfish. Some  may appear to act for the benefit of the tribe but even in the case of suicidal bees and ants, they are merely repaying a debt to the tribe that nurtured them in infancy.

The probolem with humans is that they can be persuaded to sacrifice themselves and innocent others for the greater glorification of a nonexistent deity and/or the income of a human parasite.

I think they are merely following instinct. They don't seem to feel indebted to anything.
