I cant see how you could even say that the worst thing was flaunting his theft. Wouldnt you say yes .. he did flaunt in frount of gods, which is a lack of respect if nothing else, which is abominable. However wouldnt you say teh betraying of friends, those that trusted him and defended him, those that aided him when he needed it and those that laughed, joked and played with him, is the worst crime He has broken trust, betrayed those that considered him a friend.
Broke an OAth .. the oath of citizenship. Like so many before him, Lashar and Tylin to name two, he has lost the trust of many of his peers. Who is to say he wont betray those he tried to aid, or them betray him because they now know his nature. Those that know me best would know I keep my oath's, because once they are broken who would truely trust me after that. People may say they do .. but deep down I would know they wont, and probally never will again.

Who has Borknagar betrayed .. no one but himself!
