The problem with letting it stay as is and treating it ICly is that it's a free win for the person betraying their team. Their teammates are helpless to stop them from murdering them all.

I'd honestly say until this is altered to allow any kind of fighting back it shouldn't be permissible to whip out a Betrayer's Wit and backstab your team in a serious PvP situation without prior consent. It's practically an auto-loss for the side who gets Betrayer's Wit'd, unless the enemy team is merciful and hard targets your dubious teammate.
