My first play-through I never stole or pickpockted anything or anyone, always taking the good moral path on my journey through the Mojave Desert, always backing out of a fight that would otherwise affect how the good natured people of the wastes would feel about my character.
On my second play through, I began with the intention to be nothing but ruthless with the people I meet, always taking the option to kill or harm mentally.
2 hours in I found myself not having the will-power to actually continue down this path, like I was somehow doing something "wrong", so I stopped.
Is this just me, or something different?
