You forget, this guy is western, and must be guilty of anything he could prevent.
By that standard, of course, Gandhi would also be worse than Hitler, as he could have prevented massacres during the partition that killed much more people than Hitler ever did. In fact, he is accused of directly instigating several massacres, a hell of a lot "more guilty" than Churchill would be even if this were true. If this is true, Churchill refused to get people out of a big mess they got themselves into (which, granted, does sound like something he might do).
