Several:
1) Deliver a message that such malfeasance has repercussions.
2) Put a permanent stain of humiliation on the SOB.
3) Impact his future receipt of pension from the tax payers.
4) Piss the hell out of the Wookie.
Four alone is good enough for me.
5) Eliminate or at least make it very difficult for Wookie to hold any elected office in the future.
Amen, brother!
I understand your (and my own) desire to find sufficiently impactful the call him but a Wookie isn't one of them.
The terms Liar. thief, murderer, treasonous also fall short in sufficiency to describe him.
I wouldn't even call him Satan despite the fact that he definitely is an Antichrist fully fighting against God and Israel, Satan is uniquely evil and in a class all of his own.
I firmly believe that the term Antichrist is very appropriate and he has fully earned that designation.
