An idea that species can “be meant to do x” by y has roots in teleological philosophy. Aincent Greeks believed that gods designed and meant us to live a certain way, this approach was adapted by other religions. It cannot be applied to evolution as evolution is a sequence of random events, some more likely than other.
We have evolved to, under certain conditions, when it increases our or our relatives' chances of survival or recreation, kill others of our species or enact violence against them, including the type of violence that increases the expected number of offsprings of the person enacting it, but nobody argues we should build ethics around it.
