Why you killed your mate, i can't get it.
One of the most important factors in becoming a ragged member (member with a bandana) is respecting the other ragged members. We act as brothers, and rank doesn't matter as much as in mafias and biker groups. The outsiders are to respect the ragged members at all time, especially the ragged members that belong in the leadership.
Unfortunately, I have had to kill a few outsiders that have tried to become a member already. I don't like it, though, I have to if I feel disrespected in any sort of way.
Of course, death is not the only option. There are many ways of dealing with outsiders. The most important thing is that every outsider is getting the same opportunity to become a member of the group. We don't judge by who you are, but how you roleplay and how you interact with the group.
