Torturing defenseless animals is not an inescapable facet of human nature. It's something we choose to do and be OK with.
Yes, we've developed quite sophisticated organizations to coordinate the violence, and then developed quite sophisticated weapons to carry it out.
No. There is no evolutionary benefit for raw aggression. Raw aggression appears during times of limited resources where aggression contributes to survival. Humans as all living things, are designed to survive and use any means to achieve it.
Given minimal resources we all will revert to our primal natures.

Nothing is inescapable. You are designed by nature to live out a certain lifetime yet you can escape your nature by killing yourself. This does not change your fundamental nature. We are more prone to follow our nature then to ignore it.
Those sentences seem to contradict each other very directly.
We are not living in a time of limited resources therefore it is actually evolutionary detrimental for us to be aggressive. It's not a coincidence that our popular culture de-emasculates itself bit by bit every decade. It's because we live in plentiful times and our behavior (which is conditioned through natural selection) reflects this.
