Of course ultimately, Katzav by his misdeeds brought about his downfall. But he had a great opportunity to escape total devastation when the prosecution accepted his (lawyers') plea bargain suggestion. In appeals to the Supreme Court against the plea bargain, the prosecution justified it by claiming the case for rape was weak. Here the Katzav lawyers saw an opportunity and withdrew from the deal. It was a gamble they lost. Under the plea deal, Katzav would not have gone to jail, and the charges he was admit to came without details, so that they could have been explained away as "unintended" behavior. He could have saved face, especially with his wife and family. Now all is in the open, he goes to jail, he will be subject to civil suits for acts proven in court, and he is probably already broke by his legal costs. It is probably a bad idea to gamble on one's life. Yes, you may win something, but if you lose, you lose everything.
