How exactly do you believe murder to be advantageous? Humans live in social groups. If you murder someone in that social group, you're out of the group and have to fend for yourself.
This is clearly not beneficial to the person performing the action because they lose the resources of the group. Natural selection will have favored those individuals who weren't murderers and therefore kept the benefits of the social group and did not have to fend for themselves. The individuals who get cut off from the group had their reproductive success greatly reduced and most likely they were not as successful at producing offspring.
I think it's pretty clear to see how this follows to the present day where there is a very minute amount of individuals who commit murder and when the do they are excised from the group and again why murder is considered morally wrong.
And I don't particularly see how murdering the weak would be advantageous to me as an individual, since I'm doing quite fine. Murdering a weak person would give me exactly what benefits in your mind?
Also, what is your definition of "murder"? People deem it perfectly fine to kill someone in self defense or in protection of their own family, which fits quite well with evolutionary theory and is shown in today's laws for self defense.
I'm trying to understand the point you're exactly trying to get across here. You seem to think that it's pretty easy for an atheist to just flip a switch and start murdering people whenever they feel like it, or "on a whim". Is this what you're trying to get across? What is your main point or question exactly? Ethics and morals can be explained through evolutionary advantages and also partially through human culture, so I don't know what exactly you're asking about.
