Why George Orwell called Salvador Dali a "disgusting human being"

In 1944 George Orwell wrote an essay called Benefit of Clergy, in which he calls Salvador Dali a disgusting human being. Josh Jones of Open Culture explains why:

The judgment may seem overly harsh except that any honest person would say the same given the episodes Dali describes in his autobiography, which Orwell finds utterly revolting. "If it were possible for a book to give a physical stink off its pages," he writes, "this one would. The episodes he refers to include, at six years old, Dali kicking his three-year-old sister in the head, as though it had been a ball, the artist writes, then running away with a delirious joy induced by this savage act. They include throwing a boy from a suspension bridge, and, at 29 years old, trampling a young girl until they had to tear her, bleeding, out of my reach. And many more such violent and disturbing descriptions.
