We are predators, is a part of being omnivores. Unless we could create matter with our minds, there is no escaping it. We are just what we are in the end. Is hard for me to have a conversation that would not end in a fight with someone in the "real world", so; if you escalate that you can have wars easily lighted, in the process there are deaths involved, human kind. What humans do? We are predators, regulated by our moral compass, which tries to be controlled by itself.
