My Shepard is vengeful. Not to the point of Garrus or Zaeed, but he's pretty ruthless to criminals a lot of the time. This partly stems from losing his family to Batarian slavers. He's also tired of fighting sometimes.
I took a different route. Me, I can't stand the whole "these guys killed my family, I hate all of them" background. In fact, the "my family is dead" background has proven itself to be a weak motivation for me. No, my Shepard is clean-cut, raised as a spacer, has a good family, is a good man overall...
But for me, when a good man decides that, one day, he must take evil actions and make the criminals of the universe suffer beyond the norms of mercy and taste...that's got my attention a lot more than "my family was killed by them".
