I agree, dubious. Ben is manipulative to the max. Even though he is now evading his part in the death of all those dharma people, he did kill his father personally. He knew the gas was coming and he CHOSE to take him apart from the others and watch him die. I think that's pretty horrible since the only thing we really saw the guy do was not remember his brithday and drink a lot. My father did that and I didn't gas him.
