Is there an aspect in this person's chart that makes them sexually sadistic?

Mars in hard aspect to Saturn *can* be cruel in some ways. While I'm hesitant to say this would be the case in his chart (because I'm not analyzing the full chart, rather just looking at this and one other aspect), he does have Mars in an out of sign opposition to Saturn and that opens this to such an interpretation. He also has Pluto in the 5th house in opposition to Chiron, which implies that he's not one who will ever be comfortable with a simple or trivial life.
