There is a class which is behavioral evolution from stanford which covers these topics. There are other frameworks to look at it from like individual selection theory (try to make sure your dna survives) kin selection (your family shares your dna so try to pass that on as well, even if you sacrifice yourself). There are even more ways to look but I’m too much of noob to elaborate on them. But bottom line some behaviors might not help you and your dna but similar enough dna for you to want to sacrifice yourself. Robert Sapolsky is the professor and you can find the lectures on youtube, highly recommend all though i only finished 4 of them so far.
