Quote from CaptainObvious:
The most violent among us, serial killers, by in large have average IQ's. Of course there are a few statistical outliers, but most are average. While they kill for a variety of reasons, most kill for the thrill of it.

It has been my observation that environment will determine violent criminal activity to a greater degree than IQ or race. Human beings are subject to enviromental pressures regardless of race or IQ. The birds of a feather rule is a much better determining factor than IQ. Given the right set of circumstances a killer lurks in all of us.
