One of the areas in which people seem supremely “confused” in their theology of angels is in regards to their purpose.
They say "the winner's write history," and it is absolutely true; the most egregious example in modern times has to be the mainstream (mis)understanding of Adolf Hitler and pre-WWII Germany.
Adolf Hitler was actually a vegetarian, animal-lover, an author, an artist, a political activist, economic reformer and nominated for a Nobel Peace prize.
Stalin and the Jewish Bolsheviks were building concentration camps during this time, using Poland and other neighboring countries as a satellite to attack and takeover German soil. From 1933-1940 Hitler tried repeatedly to make peace with the Jews and "allied" forces even calling for complete disarmament on everyone's part.
He was nominated for the Nobel peace prize in 1939, the very year he was attacked on his own soil after repeatedly pleading for peaceful solutions.
(Psalm 91:4-6, 11-12) Now, too often we think of angels, who are heavenly bodies, in earthly, bodily terms.
