That's terrifically reductionist, and quite probably false. There's really no good living reference from which to draw that supposition that we're competitive by nature. The marginalized groups of nomadic hunters have been displaced into territories scarcely able to support them. Illiterate and prehistoric people are invariably framed in our own context. Despite that there is a fair share of diversity, fair enough to say something like "human nature is what we make of it" and in the most literal sense, it is something we elect to comport ourselves with. In any case even if you were correct it does not mean we had ought to act as such. That is the naturalistic fallacy in whole.
