It was very sad to hear how he was killed by his wife and mad scientists. Ignorance. He didn't have a peaceful death.
And most likely suffered severe brain damage during those last hours, so the whole ordeal was in vain. A sad joke.

Killed by his wife. ALS was cause of death. Why do you say Fran killed him?
He decided to end his life, so Fran and the doctors at the hospital disconnected him from the life support machines and he's stay alive 18 hours without life support so he propably have serious brain damage. His body is cryogenic preserve but it may be useless if he had a too serious brain damage with no oxygen during hours before the cryogenic process start.
She admitted to not being able to know for certain if he wanted to be disconnected. They assumed that his answer was "yes". An assumption.
They effectively killed him. If he wanted that or not, nobody can know, and so, it remains murder.
