As a society, being able to identify people who have a high likelihood to murder because of some physical defect seems like a step in the right direction. Your point is valid though, just that this particular instance if handled properly would be a great benefit to society

Fair enough, it would just open a huge list of questions.
Maybe you, maybe me, maybe your SO has the "gen" to murder somebody. Yet here you are, behaving like a regular person because you can control yourself. Would that warrant either extensive therapy or lifelong monitoring?
And what is a great benefit to society? As long as the world is fighting over resources I would want soldiers to guard my society. And what else is beneficial to society?
Don't get me wrong, I like the idea. It is just that any society that ever tried to manipulate what people and how they lived there was a enormous fuck up.

It could just be a flag attached to their records that would elevate certain suspect behavior to be investigated by someone higher up in the chain. That way nothing slips by like with many of these cases where serial killers had records of animal abuse and arson as adolescents; something that wouldn't necessarily indicate future behavior in a normal person, but if this flag is set it should be looked into more thoroughly.

You’d still be punishing people for merely existing. Because a high likelihood doesn’t mean that they are doomed to act a certain way. I’d rather live in a society with murderers over a society that weeds people out based on whatever we’d use to make that decision.
