I'm pretty much indifferent to the whole case, but based on what I gathered from both sides, her husband was sleeping with another woman and wanted Terri to die so he could move on, and her parents were obsessive and delusional and refused to accept the reality about their daughter.
And no, if they had folded and let Terri live it would have ended up costing each and every one of you. Nobody short of Bill Gates has enough money to keep someone on life support for like 20 years. Where do you think they got the money?
And she did it to herself, too.
The case didn't deserve nearly as much attention as it got and it's just as irritating to hear about it today as it was then. The only reason anybody cared was because Jeb Bush is a gigantic attention whore who begs his brother for press coverage whenever there's a baby who needs kissing or a dull and tedious cause needing someone to whine.
