The crowd was filled with Adulation for the hero of the city.

The doctor lost adulation when he had the audacity to put forth the absurd assertion that he could siphon off the feeling of claustrophobia using a pill that left patients feeling tumultuous, and apprehensive about his credibility as a doctor.

Courage is acting in spite of fear. SO when Lincoln helped the 13th amendment through even with severe opposition. Or when a robbery happens and a citizen stops it, without regard for consequences.

I know all of them.

The bellicose comedian was very facetious, until the crowd usurped him from the stage.

"I love to talk to my dog, which is strange I hear. I don't know where society got so judgemental."

A hero is someone who puts others above themselves, without regard for personal consequences. Because they aren't self-serving, and will go to any lengths. That's a true hero.
