(not the person you're replying to) I can't deny there are ethical problems, but on a very personal level I strongly agree with GP's premise: if I was sentenced to life imprisonment, I would consider it so intolerable I would want to kill myself (especially true in specific countries with notoriously unpleasant or corrupt prison systems). I'm honestly not sure how that should square with potential ethical problems of prison euthanasia but I feel compelled to point out that it's a real desire that deserves consideration, just like normal euthanasia. Similar problems exist with regular euthanasia and they tend to be mitigated with policies like waiting periods, redundant consent, and minimum requirements.
