Sadly, he can’t receive justice from behind, with no forewarning, like the murder he delivered to two heroes. I’d like it better if he was told in advance that sometime in the next 3 minutes he was going to be executed; yeah, perp, you can watch that big clock on the wall while you wait.
But of course that would vitiate it all because it would not be justice. Justice flows from God, and vengeance only after this mortal coil. It does illustrate a fallen human mindset.
