They weren't. Intelligent people can be anti-social too, and usually with terrifying large scale outcomes.

But thankfully, most crime in the aggregate is done by unintelligent people.

If a child shows some sort of exceptional proclivity for academics, then I strongly believe there needs to be an examination for empathy and pro-social behaviors prior to being enrolled in some sort of advanced program.

That is a tough one. For I believe there is more to reality than what data can currently capture. While I do agree that most violent crime is carried out by unintelligent people, there is an untold amount of crimes being committed by individuals that are average to beyond intelligent. So, I would argue the unintelligent ones get caught more frequently and that skews the perception that they commit more crime.
