>What if you just solve the problem by making society a better place?

Because I don't know, and I don't think anyone else knows, how to better society in a way that wipes out all the dictatorships and malign powers of the world that mean to do us harm merely for their own gain. Ultimately the world is not always a friendly place, and sometimes if you aren't the shark at the table, you're the fish.

This is true for the vast majority of people, but some percentage of our population will have Psychopathy/Sociopathy/Antisocial Personality Disorder.

There appears to be a genetic component to this, so it seems like no matter how nice we make society we're still going to have to deal with these kinds of people.
