because I simply can't imagine what it feels like to be sitting in one's cell knowing that it will be over soon
Life in prison, especially years in solitary is far worse if you ask me. Imagine spending a year or two in solitary? 23 hours a day by yourself, with nothing but your thoughts. Most people end up losing it. For prolific killers or people who need protection, this is more common to end up in such a situation. It seems far less humane to do that to a person then to just put them out of their misery, if you ask me anyway.
Yeah, I never understood solitary confinement. I mean, if he did something so bad that he needs to be completely isolated, why not just kill the poor bastard?
