Exactly. I don't know how much blame Sam Winchester really has, but I'm willing to wager a lot. Ruby reminds me a lot of someone I knew back home, a creature named Vergere. Vergere used similar manipulations on me, set me on the path for the Dark Side. But I don't place the responsibility for my actions on her, they fall on my head and they are for me to atone for. So no matter what Ruby actually did to Sam, the damage he's done to Faith is on him.
Well, we're from a galaxy a long time ago, far far away if you listen to that Lucas guy. My sister's called Jaina and my brother was Anakin. To us, that's just normal and Wesley's weird.
