He actually tends to dwell more on the violence related aspects than anything in that interview.

But remember too that he is an out and out psychopath - he knows he is entertaining Dobson, a religious nut, so as psychopaths do he tells him exactly what he wants to hear.

If an atheist group came in to do an interview the next day he would be bashing religion and blaming all of his problems on it.

That is just how psychopaths work, they are manipulative by nature. He didn't lure dozens of adult women into his car by being stupid.
