The violent societies have also been wiped out and dominated by other violent ones. Or have caused their own collapse by other means. So violence has not yet shown itself to be a successful strategy for societial survival.

Survival, it turns out, is a game one cannot win. Everything and everyone comes to an end eventually, even the universe itself apparently. Justification of violence on the sole grounds of continued survival is therefore very suspect.
