Consider Japan, who does it differently. Death row inmates in Japan are not told their execution dates, as they had issues with people committing suicide before they could be executed. So now they only find out with just a few hours of notice when they’re going to be executed. You could be sitting in your cell, ten years into your sentence, enjoying an otherwise ordinary, quiet day in prison, only to be told that it’s time to die, whether you’re ready for it or not, the equipment and staff are already prepared and there’s no time left to argue your case.

Honestly, I don’t know which one is “better”. They’re both cruel in their own ways.
