Granting that Montt (who btw was an ex-Catholic and a Pentacostal)  was a war criminal who was supported by a U.S. president, what does that have to do with the communist Guatemalan death squad that killed fr. Rother and other innocents?

The author make a vague argument that the "complicity of our culture" led to the murder of this priest.   I don't follow his logic.   If Montt was a war criminal, then it's justified to kill Catholics who are simply trying to help the poor?   How so?

Or if the Catholic Church is anti communist, then it's necessarily complicit in the acts of war criminals who fight communism?
