Michael had abandoned his wife for another woman - he had been living with her for years before filing to have the court order her death. Those are the facts - the only person being hysterical is you.
WRONG! I am not the one posting photos of Michael with horns on his head as "SATAN" and labeling him as "EVIL" etc as some are doing here. THAT'S HYSTERICAL.
Furthermore Michael sought out ever means of medical help he could find for Terri for the first 3 years.
Then he gave up.
I think that is MORE than reasonable.
