I am so holy as to judge him.
Cheating is morally reprehensible, and more over, it fails to take into account his wife's feelings; and more importantly her life in general. Tiger ruined his whole life by siding with passion instead of responsibility. By not "overblowing" this, it would be akin to encouraging cheating, and showing how there are no consequences. There ARE consequences, and it is one of the most repulsive things a human can do.
Truth is, most people think it is wrong to cheat and thus, they don't do it. Therefore most people are fit to judge Tiger.
People who cheat should all be treated this way; worse in my opinion. It is utterly inconsiderate.
