IMO, that's "exactly" what he thought. He's a complete narcissist and his ego is so inflated, he thinks everyone who just listens to him will respond in the way he wants. To put it simply, he has a god complex.
Here's a definition.....sound familiar?
A god complex is a pattern of behavior characterized by an inflated sense of self, power, and entitlement. People with a god complex may believe they are superior to others, have great influence, and are infallible. They may also feel entitled to special treatment, disregard the needs of others, and act as if rules don't apply to them. People with a god complex may also be highly dogmatic in their views, speaking of their opinions as if they are unquestionably correct.
