Is there anyway to kill your own gang members or join o.Driscolls? I’m in chapter 4 and I Will not help my gang a singel bit any more. I was hunting for a 3 star buck for 1.5 hours when I finally found one. When i was going to put out my gun a ”event” started and Micha (or someone from the gang) come frome nowhere and asked if i should come back to the camp soon....???? The buck run away, 1.5 hours down the drain.....WTF??? The game is probably over for me at this point since i doubt that there is any way to kill your own gang members and I won’t do a sh*t with my gang anymore....
