Because they don't care if it is not them
Envious, maybe you have the wrong bible version on?
Elie Wiesel is a survivor of the concentration camps in Germany. In his prologue in Night, he states he doesn’t consider himself a hero. He doesn’t think he’s a hero because he saved many lives. He did what he had to do, not for fame. A hero is someone who saves lives, even if it means endangering your own life.
It's more important to what a person does because as they say, actions speak louder than words do. A person can think a certain way but not act on it but what a person does reflects what they decide internally and what they wanted to do with that idea externally showing that they are serious with that idea of theirs in their head.
