At the end of the game when you meet Kerghan... and he tell about his philosophy... Then you can choose to join him or not... Now I won't ask if you did join him or not, Cause then we are talking about your character... I know it might sound weird but... I couldn't help but think, if I (myself) was to decide whether or not I was going to join someone like Kerghan, what would I choose? I myself would say yes (seeing as I have a lot of the same philosophies and viewpoints as Kerghan has himself) What would you have choosen? (Not your character, but you yourself as a person...)
If you'd join him, you'd have to always keep an eye on him. He is an unreliable co-worker. In fact, if you join him in the game, later he... .
