Gurgi not let his friend die. Taran has many friends. Gurgi has no friends.
~ Gurgi about to sacrifice himself to the Black Cauldron to save Taran
These are pretty much the opposite of selfish heroes and egomaniacs. These heroes rather care more about other people's life instead of having an ego. They will put themselves in trouble to save others, even if they are a villain or enemy. They would even be willing to sacrifice their own life to save another or more.
