It seems most of Bin Laden's family wants nothing to do with him (Osama) or his actions. And thus we should not paint the son with the sins of the father (we are not Klingon after all),
However, I understand your point, and actually feel sorry for the man. Regardless of how he tries to live his life, the fact he is the son is going to hound him all his life, and thus through no fault of his own, he will be stigmatized by his birthright.
