It could be noted that letting your sense of human compassion overrule your sense for righteous justice could be a mistake.

I've got lots of compassion for all the Murderers, Rapists, and suchlike out there. As do I have compassion for the Traitors. But to my lights, Our Lord's Justice and that of this world may be two different things.

If he's truly repentant, he can go to Our Lord with a smile. As can all those who we have to execute.

OTOH, if you did it here "Under the Sun", you have to deal with the consequences that you get here, too.

I sincerely hope he never sees daylight for more than one hour a day ever again in his life.
