Hmm... it's not the relations with dictators that I find so repulsive, nor even her absolute opposition to abortion. Those might be what you call "slip-ups".
But she did, in fact, preside over awful standards of care, people were denied access to medical treatment, and suffering was not alleviated, because it was considered "spiritually noble". MT also campaigned agains family planning and contraception. So while, by religious lights, she might have been "moral", the effect was deeply cruel and wicked, keeping people in poverty and away from real medical care.
Also, if you want to take issue with Hitchens,I don't really think you should imply that Henry Kissinger was among the better specimens of humanity! Nor, for that matter, was the previous Pope (whose time in the Hitler Youth one may overlook, as the actions of a child under compulsion, but who fully deserves to go to Hell for knowing inaction on child-abuse, and opposition to condoms despite HIV).
That said, I do entirely agree with you that nobody is perfect and anyone can be made to look bad. Your "exhilaration" quote is one example... I checked the context of this, and while I don't find it in good taste, it's not an uncommon description of how some people feel at the start of a war, even those on the good side.
(You might consider imagining yourself as Churchill, at the moment when Hitler invaded Poland - a rather strange mix of gloom at the inevitable impending tragedy, combined with some excitement that, finally, because the evil thing has become so bad, that the world can delay acting no longer and that it will stand up and fight.)
