> It seems more cruel to lock someone up for the rest of their life with no chance of parole AND denying them the ability to commit suicide.
It does, but at least it is reversible. I think when the worst case (an innocent being killed) is so wrong, it makes sense to design the system to avoid it, even if this has side effects such as making it worse for the actual criminals.
I would support leaving the opportunity to commit suicide in good conditions rather than strangling themselves with their bedsheets, but doing that properly would be tricky.
> Maybe avoidance of cruelty isn't the point of getting rid of the death penalty, though.
That’s a tricky one. It is hard to want to avoid cruelty in the case of gruesome murders. Nobody wants to say that they want to make the life of jailed terrorists better.
But among the opponents to the death penalty, I don’t think that cruelty is the main point. By keeping them alive, we don’t lower ourselves to their level, we leave them an opportunity to become better, and we avoid the moral cost of killing innocents.
Besides, life in prison is as good or bad as we collectively want it to be. There is a spectrum between Swedish jails and a hole in a dungeon.
