Everything bad Ross has done has all been driven by his hate for Pete and wanting to get revenge on the brother that left him for dead. Everything bad Robert has done has purely been about trying to keep his affair secret and to get as much money off the Whites as possible. Yes he may not of meant to kill Katie but he pushed her around threatened her and would quite clearly of done everything to hide the fact that he is gay. I like both Ross and Robert but to say one is a social misfit and the other isn't just ddoesn't make sense.
