Gster, if everything is the same from both sides, that means we should hate each other equally. When you approach Outcast about peace, he will refuse. But when you approach us about peace, we are willing to listen. See the difference? It is not equal; Outcast is the biggest obstacle to peace.
The funny thing is that we have a stronger community than he does, we are in the position of power, and yet he is the one who doesn't want to make things easier for his clan and make peace with us. It's actually rather comical. He is a poor leader; I feel sorry for his members.
You will never be able to get Outcast to be respectful and work for peace, because he believes that he is the key figure in all of JK2. He needs no kindness, approval, or cooperation from anyone else, and his world is absolute.
I respect that you try, but I recommend that you give up. You are likely wasting your time; it is impossible to reason with an unreasonable man.
