Humanity did not remove itself from the food chain on this planet by being stronger than tigers, bigger than lions, tougher than wolves, etc. We did it because we have evolved to be so competitive that we will tear each other and anything else to pieces over just about anything we want, real or perceived, to a far greater extent than any other species. We are brutal, nasty, hyper-competitive animals
with the potential to be better. The Vulcans also understand how humanoids are driven by desires:
Spock: you may find that having is not so pleasing a thing after all as wanting. It is not logical, but it is often true.
