This has nothing to do with putting Woods on a pedestal. She was a swimwear model, for goodness sake, not the living incarnation of Florence Nightingale. Angel, floozie or the second coming of the Madonna, she's not remotely earned half of Woods's income over the past 5 years. The kangaroo courts we currently have will disagree, of course, so she will get her pound of flesh, and then some.
Regardless how religious or romantic the ideals may be, marriage is a legally binding contract. You stand before God and man, pledge your fidelity until death do part. Breaking a contract costs money, the more money you have the more it costs, add intentional tort (the cheating) and punitive damages are awarded.
She modeled some swimwear, that does not make her evil, in fact, it was probably part of the package that Woods wanted. She gave him a couple of kids, she was never acused of cheating and by all appearance was a loving wife. She apparently was doing her part. If things were not good on the home front, get some counselling, quietly get a divorce, deal with it like an adult.
If your wife has to read about your 3-fers with hookers and hear your girlfriends complain about being cheated on, well, she has her pound of flesh coming.
