Is Levine Just Committing This Crime?

Moss goes through a place of like rage and despair and anger. But also there's an interesting question of is he just performing that because in fact he's just committed this crime. There's so much smart psychology in the movie. The other thing too is I think that that closing sequence with Levine and Williamson, when Williamson sniffs out that Levine did the robbery,. which then leads to that like heartbreaking exchange between them.
