Quote from: Local Trouble on Today at 05:02:30 AMDillon pretty clearly demonstrated in the movie that he was not only no longer a rapist, he actually saved her from being gang raped by men that he considered his brothers.
Also stops himself short of killing the rapists.
Dillon is the embodiment of the film's thematic argument. He has absolutely rejected nihilism and the destructive/ self destructive potential of nihilism. He will literally beat the nihilism out of you if he sees you abandoning your moral principle. He will not let you check out early and let other people deal with shit. He will not let you die on your arse doing nothing.
And all of this is made stronger by the fact he has clearly embraced nihilism in the past, and learned to overcome and reject it.
