I have to admit, I got a bit hacked off by the Diamondback Militia Officer ranting on about me being no better then a murderer for killing his men in the Canyon, so I better help their plans or they'd just put me down. And if I got killed in doing it, so what.
Given the fact that his men attacked you regardless on seeing you, I'd say it was their own damn fault. So, since I'd already hacked all the turrets in their base, I used brawl to take out a couple of DMB folks, grabbed their weapons and managed to kill everyone else there.
Of course, that didn't stop the DMB and Bandits and Monks fighting over everything after I disarmed the Nuke.
So does slaughtering everyone actually change any outcomes?
