Does move on with your life mean "go ahead and dispose of your inconvenient wife?"
The Schindlers told Michael that it was time to move on. Find another companion, when it became obvious that Terri would never be able to provide companionship. They testified to this under oath.
You may read into that what you wish. But her very own parents testified they knew there was no hope and understood MS was too young to remain without a companion for the rest of his life.
The Schindlers also testified that even if they KNEW that Terri would NOT want to be kept alive in that condition, they would keep her alive.
They further testified that even if she needed multiple amputations as a result of poor circulation, they would keep her alive. That's not love. That's obsession.
