If you wish to stop this there are 2 ways and i have done them both sucesfully one either destroy the village after talking to min gord with the help of the Orgs or as soon as he speaks do not reply to him instead hit the pickpoket button and start taking his stuff this will end the discusion and he will stay in your group
Keeping Virgil There seem to be several ways to keep Virgil and not all of them are due to quirks in the game interface. Since some are due to valid game choices, I think this is just a little known branch point in the story. In my current game, I kept him with my party and we both just hit level 50. So far, I have not come across any glitches in this story line, you just don't find him later where you normally would.
Yea, the 100% evil, and the kill stillwater are the 'evil' path, it's really where the two paths branch. But the other one, about pick pocketing ruins that intersting storyline.
Another branch I've also found that Virgil doesn't leave if your fighting your way out of the city. See my entry on the tips & strategy page.
well i only discovered that on my 4th time through playing the game with the pick poket thing stilll trying to get use to their world builder to make a few mods but its frustrating
