I agree. I think this is supposed to be a combination of the old (ancient demonic aristocratic blood sucking monster) and new (But he's still "troubled", handsome when buffed to full strength, and kind of good! Er,at least better than Satan!)
Either way, we're supposed to be playing a flawed tragic character much like Kratos was. (And I don't know why Mercury Steam gets upset with God Of War comparisons because controversy aside,it was a great series. To be likened to God Of War is an honor,really. Though admittedely the word "clone" often has a negative connotation.)
