From an evolutionary standpoint that only has value if creating a species where people are more emphatic and respectful means an increased survival rate. If cheating, lying, disrespecting others, means a higher survival rate or increased chances that our genes get passed on, then biologically speaking that's all that matters.
That is absolutely true, but no one has shown that the development of ethics (and in turn, the intelligence to create a system of ethics) has been detrimental to survival.
