"What is a better angel?" Very difficult to tell, might not even be such a thing, but possibly it depends upon who you think you are. It could be argued that better angels are defined by those who hold political power, or who are granted political power, or take political power, or inherit political power, or find it under a rock somewhere.
I could go on about how Constantine's deathbed baptism made a mockery of
his Treaty of Milan. The result was the theft by the powerful of an idea that
gave succor to the poor, the hungry and the disadvantaged. But one things for
sure, it's difficult to conceive of a better angel chanting "USA, USA, USA"
while beating up on Black People in Tennessee.
