Best outcome for them is Magni's character dies, the others gtfo, and Magni makes a new character. If you want to play evil or amoral character then make them evil or amoral, don't make them technically good and pretend like they are good, but are free to do whatever evil shit they want at the drop of a hat with no repercussions. If they wanted to be evil murderrhobos i am sure that Vesper could have written a campaign where they were free to be that.
