He even got the Tuco treatment from clint at the end of the film.
That's not a fair comparison at all.
In GBU, Blondie wanted to make a clean getaway without Tuco shooting him in the back;
that's
why he forced Tuco, at gunpoint, to get up on the cross and put his head in a noose.
Here, other men tied Silvanito up and hung him up; Eastwood shot him down to save him.
Totally different circumstances.

Silvanito does seem grateful that his town will finally be peaceful thanks to the Man With No Name.

I like to think that Joe may be shared some of the fistful with him.
