Many victims of race-based prison rape turn to racism and murder to "avenge" their perceived loss of manhood. See:

From the article:
"A Monstrous Crime
While I was on a speaking tour in Texas for Amnesty International in February, 1999, I met the parents of a prisoner who confirmed my suspicion that John William King was most probably sexually assaulted in prison a few years earlier. King, you may recall, was the young, white man recently convicted and sentenced to be executed for dragging to death a black man last year in Jasper, Texas. This prisoner, once confined with King, told his parents that King was probably gang-raped by members of the Crips, a nationwide gang of blacks. King was just an average, Texas, good ole boy, redneck racist?not a particularly mean one?when he first arrived in prison, the prisoner reported. But soon afterward, King was ?turned out? (raped) and turned vicious."
It really is a vicious cycle of violence and hate. Maybe its time for prison reform?
