Animals that live in social groups tend to be nice to each other for two reasons:
1. It is mutually beneficial.
2. Your relatives have the same genes as you and benefiting them is benefiting your genes.

Social animals show certain predictable patterns of behaviour including:
A. favouring close relatives over less closely related individuals.
B. a delicate balance between selfish competition for mates and resources and altruistic behaviour. Game theory can be used to study the best strategies - and demonstrates that some amount of selfishness is to be expected.
Overall human behaviour is very similar to that of other social animals and is well explained with evolutionary theory. It is very poorly explained (or not explained at all) with theology. Theology utterly fails to explain bad behaviour, always trying to hide it behind the curtain. Common attempts at hiding it include a 'curse' put on the world because Adam ate an apple, or the influence of Satan the arch example of bad behaviour whose on bad behaviour is left unexplained.
Nothing is said in theology about favouring of close relatives.
Human sexual behaviour is also well explained by evolution theory - right down to the differences between male and female behaviour, and totally unexplained by theology which struggles mightily with it.
