My family and I have had to make such a decision.
Would you like to charge me with murder?
really? so you decided to petition the courts to withold food and water from your wife? you let her starve and dehydrate to death, slowly and painfully? And did you have any evidence that she wanted to die in a way that we are not allowed to do to dogs and prisoners in this country?
If so, then yes, you should be charged with murder.
There is clearly so much you don’t understand about what happened to Terri.. she was NOT on any life support (unless you count food and water as life support), and there was no evidence (other than the word of a cheating, abusive husband) that she wanted to die in this horrible, painful, slow fashion.
Catch a clue.
