They absolutely need to sue Iok for all the damages. That guy is totally intentionally causing so much trouble. In fact they should arrest him and throw him into some pitiful, vermin infested cell on Mars, to wait for a trial. It would suitably ruin his reputation further. I'd like that much more than a simple death. Although even if he does die, they should spread the news how this all was his fault, so that he would gain no honour from dying fighting.
