I don't know what you're trying to say. That violence has been used as a solution to problems? Sure. It has. That violence has, rarely, in some cases, been a sufficient answer for a problem? Sure. You cited a few. But that's not what you started out saying. You said that violence has "solved more problems in human history than any other solution" which is ridiculous.

Oh, and I don't think hunting animals for food is the kind of "violence" we're discussing.
