Funny you should say that, because
I made an entire thread to let people say what they would do to the traitor a couple of days ago, and that was pretty much one of the things people could vote for. I know this kind of character is not for everyone, hence why the punishments are mostly non-sexual (exile, execution, imprisonment, Mark of Cain, slavery etc.) although some paths were also intended to leave him open to interaction in future for those who wanted it.
Besides, if you think you hate him, just imagine how ballistic the
king is gonna be when he finds out. I wouldn't want to be in the traitor's hooves on that day.
