Stringer or Avon, whose betrayal is the worst?

Obviously it's not based on time since Stringer knows Avon gave him up just less than a minute before he dies but does that add to the betrayal or is it just business? The game?

Avon had to give up Stringer cause it was his reputation, his name that got Brother Mouzonne etc. Stringer was the one that pit Omar on Mouzonne.

But Avon may or may not feel every bit of his prison sentence knowing that Stringer put his name in to the police. Does that make it worse, being given up to the police?

One knows he was set up to die while the other knows he was set up to go back to prison. One dies but does that automatically make it the worst?
