Crimes have punishment. When the penalty is paid then people move on. IRL Murder is often a life or death sentence. The CF equivilant for a Maran would be to never forget and keep in pursuit.

For a Tribunal his duty is fulfilled just by placing the mark. There's nothing in his cabal dogma that says he needs to even pursue a criminal. So he would be free to chose what he wants.

And the Maran argument is that they aren't even allowed to hunt the nexus. Or so it was but there seems to be a slight retraction of that now.

I'm stupified about how narrow the field of view is with so many people here.
