Characterizing Edna vividly as mercurial, liable to change temperament any time, is another challenge to stereotypes about aid givers. While her sacrifices make Edna appear saintlike, she also erupts at the staff who care for her patients. This shows both the humanity of heroic figures, and that efficient change sometimes demands impatience, not saintlike calm. An alternative way of looking at Edna’s temperament is that saints are not required to enact change:
any person with sufficient drive and willpower can create change.
