And the oblique commentary on the caricature he played in most of his spaghetti westerns.
No fancy shooting (the hangman's rope, the bullet through the hat, etc.).
Instead, he gut-shoots an innocent kid with a rifle while hidden away in the rocks. Cowardly act in stark contrast to his usual bravado.
Same thing when he murders the unarmed Skinny in cold blood, and when he finishes off Bill.
A former drunken murderer turned pig farmer with a conscience.
"I ain't like you Bill."
"It's a helluva thing, kilin' a man ... you take away everything he is, and everything he's gonna be."
And then he goes into town ...
So many levels.
Superbly written movie!
