That strikes me as more of a burden than closure. But that's me. I would second-guess myself horribly, trying to decide if i really thought he deserved execution or if i was just being vindictive.
Or if i let him off, am i convinced of his innocence, being compassionate, or just squeamish?
Plus, good God, can you imagine the emails of everyone with an opinion on the matter, before and after the execution or release?
'You should,' 'you shouldn't,' 'you gotta,'
'be a man,' 'don't wimp out,'
'god wants you to love your enemy,' 'god says you can take an eye for an eye,'
'you did good,' 'you did it wrong,' 'congratulations, you're about as civilized as Stalin,' 'way to burden society with your mistakes, asshole,' and so on....
