We'd certainly fault him if he married Katrina vander Heuval, for his complete lack of common sense.
You know, it's not like Giuliani was drafted into his marriage. He CHOSE to commit himself for life to that woman. He wanted to do so very badly, so much so that he went through the trouble of manufacturing a reason to get an anullment so that he could marry her in the Catholic Church.
The Catholic Church determined that these two people were meant to be joined together until death did them part, partly because the two of them testified to the church officials their intentions to do so.
Nobody held a gun to Rudy's head to force him to marry this woman. And he wasn't some naive kid either, he was a grown-up who had been married before and therefore had experience.
I feel no sympathy for him over how his wife turned out to be. I may forgive him his divorce, but don't ask me to cry a river of tears like he was some poor emasculated sissy.
