What ideas about human nature does Taylor's statement, "It's a sad day for us all if I'm being a hero here," relate to?

I think this quote represents the idea that Mattie, Estevan, and Esperanza all take risks and make sacrifices for others.Taylor thinks that her experience pales in comparison to the heroics of the others. Mattie runs an illegal sanctuary for refugees and Estevan and Esperanza risk capture when they help Taylor become a legal guardian of Turtle.
