Stanton's got it right. The whole point is that the outlaws aren't a threat. It's even hinted that the outlaws are victims of political or religious persecution rather than criminals. CJ's way would be more morally ambiguous, but I don't think Corbucci was going for ambiguity.
My trouble with that is the old Utah Territory, the surrounding environs of Nevada, Northern Arizona, and Southern Idaho are Mormon-ized so it doesn't quite make much sense to just hint at it when you could have say tied in some actual historical incidents like the Edmunds Anti-Polygamy Act of 1882, passed in a wave of Victorian-era reaction to the perceived immorality of polygamy, or the Edmunds–Tucker Act on May 19, 1890, that dis-incorporated The Church of Jesus Christ of Latter-day Saints, or even the non religious Ludlow Massacre in the snow on April 20, 1914 where workers at Colorado mine went on strike, company guards fired machine guns and killed several men, 2 women and 11 children.
What we get instead from Corbucci is a total out and out fantasy, with a fake epilogue, when it could have been so much more.
