I will steal and pick pocket from people, ask for money for what I do for them, but I avoid killing at all costs generally. I get caught stealing oblivion, run from the guards, never kill. In fallout new vegas, I got really good at pickpocket and stealth, to avoid killing unnecessarily. And when given the option, like in dragon age and mass effect, I do not kill wrongdoers generally .
However, I also can be completely driven by vengeance, and just blood rage due to committing atrocities. When Caesar's army killed and crucified that city, they told me to tell everyone. I chose to kill them all. I used all my ammo and all my stimpacks and all my food, but they died. That's all that matters.
In conclusion, naturally I avoid senseless killing, stealing I engage in, and sometimes ask for money for the good deeds I do. However, push me, and I will kill everything you love.
