While it is illegal for Scott to kill his father, or allow the doctors to kill his father, it is not illegal for his father to engage in highly dangerous behavior.
If this were my dad, I would leave him alone in a house with lots of clearly marked poisons, and warn him explicitly not to drink any of them because I absolutely do not want him to drink any of them, and then I would go for a really long walk. It would be a shame if I were to come home and find that he had accidentally taken a drink of poison instead of his beer. A shame.
