For the former skinhead, it gives him a chance to atone for any misery he may have caused other communities. I can tell by his actions that he couldn’t be sorrier for his actions in the past, and how they scared others from outside the White race. Additionally, while he did not know the perpatrator of the Sikh Temple Shooting personally, the event scared the former supramcist by making him realize he may have been an influence on the guy pulling off this unspeakable horror.
As for the son of one of the victims, to team up with this former White Supremacist seemed like a difficult decision at the time, but now it pays off with more advantages than not. As a victim of White Supremacy, it can help educate others as to why more needs to be done to stamp out this old plague of the past. The victim has a strong story of how his father was murdered for no apparent reason other than he was not White nor Christian.
