I understand the concept and reasons for not having capital punishment but why do serious offenders like a serial murder have to be saved and given the best medical treatment?
There are millions of law abiding citizens who have no access to medical care and many die from their natural diseases everyday.
They're already being fed and provided a warm place to sleep, which is already better than what a lot of people who never break a law get. If someone like Manson gets a natural disease that many normal people die from everyday maybe he can be afforded the same treatment regular people get as well and succumb to the disease? I'd much rather have my tax money go to providing care for people who don't murder people than the people who do.
When we as a society imprison a person, we assume near total control over their lives and environment. There's a corresponding responsibility attached to that action.
To put it another way, a prisoner has no alternatives. If they are not provided medical care by the state, they have no other way to get it. It's not merely an absence of assistance but an active prohibition. We don't consider the prevention of needed medical care to be an ethical or appropriate punishment.
Our apathy and lack of care for people who need care and haven't been imprisoned is shameful to the extreme, but also a separate issue from the responsibilities created by using imprisonment as a sanction.
