That's their decision and theirs alone to make. They should not be influenced by outsiders. They've been through enough. I'm concerned about Mr. Schindler. He health must have taken a terrible beating.
Nothing in their lives prepared them for what they've had to deal with in the years when they should be having some peace in between the normal blows life gives everyone.
Some will say they brought it on themselves and question their motives. BS. Whatever their motives are, they have fought harder for their daughter in an unprecedented, prolonged manner.
If the Schindlers think their anger towards Michael Schiavo and others will be assuaged by filing a wrongful death suit, they're sadly mistaken. They'll only become more angry. If they're using the courts to punish and destroy him, they'll never get satisfaction. However, because their lives for so many years has been spent in the courts battling him, they don't have any other way to live. This is their normal.
