Soooo ummm.... All these people goes to rescue one person and dies trying to rescue that person?

I understand if that person was a leader, king, or present but losing 10 men just to rescue 1 man doesn't seem worth it. Now you have to go back home and tell all the families of those 10 men that they aren't coming home. I watched that movie Bone Tomahawk. The sheriff's wife tells him not to go but he still went to rescue the doctor anyways along with her husband and some other men and he dies. Then I remember all them other movies were a group of people dies trying to save 1 person.
