In the trivia, it is stated that there was an extra scene at the end of the movie where Derek is seen shaving his head again, but the scene was cut because it was deemed "pro-Nazi". It is left ambiguous in the film as to whether or not Derek intends to revert to his old ways. While in prison, Derek learned that hate is a waste of time and that he only was acting out because he was angry about his father being murdered. He came to realize that not every black person was like the one who killed his father. He tells his story to Danny who, by the end of the film, obviously sees the light, but in a tragic twist of irony, Danny is gunned down by Henry, a black person he had earlier insulted. It isn't unthinkable that this would distort Derek's perception and make him believe he was previously right. However, once someone has an epiphany and their mind is opened up to such matters, it is rarely closed back up. Yes, Danny was killed by a black man, as was their father. However, Derek would still understand that not everyone was like that. Dr. Sweeney is a perfect example as he wanted to do nothing but good and help troubled youths. The last line Derek says in the film is (knowingly) "Oh Jesus. God, what did I do?". In this it could be implied he does not revert to his old ways but blames himself for what has happened. This would mean he would not revert to his old ways as his brother's death would be in vain. Henry killed Danny as his vengeance for Derek killing and curb stomping his brother. Derek would probably realize this not long after the situation and see it was his doing that led to his brother's death and he doesn't blame Henry as much as he blames himself and therefore would remain on his new path of righteousness.



Furthermore, it's probably implausible for Derek to want to re-associate himself with his former neo-Nazi cohorts, given his experiences with them during his time and prison and immediately after his release.



It is also important to note that Derek, when posed the question from Dr Sweeney "Has anything you've done made your life better?", Derek tearfully and genuinely responds that, no, it hasn't. It's safe to say Derek has well and truly changed his life outlook from that point. Edit
