If a convicted murderer/rapist/molester serving a lengthy sentence has expressed a desire to end his life......

As a taxpayer I can see the reasoning where it's a waste of our money to house them in prison for life, but there's also a reason why it's called punishment for crimes committed and them committing suicide is just a way for them to get out of their punishment early. If they are permitted, it should be done humanely like slaughterhouses do to animals, bolt gun to the head then cremate the remains and flush them or put in a compost pile... 🤨
