I think any creature evolved through competition and natural selection will end up this way.

Lying, killing, stealing, loving, building community, etc. are advantageous to survival at different times and in different situations. Seems the best survival tactic for us was to just keep improving and blending these.

We are at the point in our development where a lot of them don’t fit as well anymore. But they won’t go anywhere unless they impact mating success or stop being passed down for genetic reason.
