I think that you seem to be missing the point...
We can rise above settling disputes with violence.
As I say, that a nice ideal. Sadly, its not true - without the threat of punishment, people descend into barbarism.
So, in other words, you're saying that it's better to preempt violence with violence rather than to meet violence with violence?

Of course. That's why we have police, social services, welfare services and mental health services. Take any of those away and you will live in a far more violent world.
