((I'm the sentimental sort that likes the idea of bad guy turned good.  In the end the choice is up to you...you also have the factor of revenge to consider though.  Has his mind been going through the motions of how to torture Fexiryn for what shi did to him or has his extensive time away from the school given him time to settle his mind down and come to a realisation that he doesn't need revenge anymore.  I like the idea of a final battle where everyone bands together though.  ^_^  This is coming so close to the climax I can taste it.  *lol*))
