[A long pause. Sasha's spoken to Will enough to realize that's more because he's thinking his words than he's ignored her, or having troubles.]
Because he's a sadist [Does Sasha know that word? Maybe not. But Will doesn't ask, keeps going.] and he's obsessed with fear. Knowing you were afraid, what you saw, is part of his design. People like Doctor Crane care for others when others can provide them with something. In this case, the reactions and results to his attack. He may have lost the capacity to relate and care for others outside of that.
[Or he may have had it taken from him, Will doesn't say. He doesn't want to get into relating to Crane, not with Sasha.]
Remember when Doctor Crane told you we all have monsters inside of us, and that doesn't necessarily mean anything bad? Now you have a better understanding of why he'd think so, and what his idea of the "greater good" is.
