I would say "I judge it made him blind" shows the realism of this man's seemingly angry state. The speaker sees that this man's anger has exceeded his "mental vision", shall we say. The man isn't sure of what he's doing, except that he must do something to feed and calm the anger.
I'm sorry if this doesn't help, but that's how I see it as realism.
