Regarding Peter and him crying.
When Peter was crying before Paul interrupted him to (apparently tell made up) stories about him, what do you think he was meant to say, what was it in him that later turned him into a sadistic psychopath and what kind of traumatic childhood or life did he have?
Did his parents really abuse him and did he have a drug problem, was he in some or other ways confronted with his sexual orientation or was he perhaps just putting on an act to ensure that during the whole torturous ordeal, the family ends up being sorry for him and doesn't get a strength and a desire to hurt him even in self defense, regardless of whether or not its all true and that there really IS a motive or a reason these two people turned evil psychopaths?
