I believe it's called 'Self Delusion.'
If we evolved so highly to create a moral code for self-interest than why haven't we evolved to not need the moral code and just
be good instead of lying, committing adultery, murdering, stealing, rebelling against our parents, and coveting others possessions? Not to mention wars, genocide, indifference to suffering, etc that is so characteristic of the history of the world.
How do we even conceive of "good" or "bad" if we're just animals living an accidental existence. This is where stevebaby usually jumps in with his thoughts on how the love of his children (that I assume exist because he knows who The Wiggles are) or family is just biological so we reproduce. As if people who don't love each other can't reproduce.
By the way, it's in my self-interest to procreate over the weekend, but I'm going to need to steal your car to get to the desired genetic material. I'm sure you won't mind - it's not like it's "wrong" or anything.
