Maybe you are saving someone because you’re a strong, generous, well-put-together person who wants to do the right thing. But it’s also possible—and, perhaps, more likely—that you just want to draw attention to your inexhaustible reserves of compassion and good-will. Or maybe you’re saving someone because you want to convince yourself that the strength of your character is more than just a side effect of your luck and birthplace. Or maybe it’s because it’s easier to look virtuous when standing alongside someone utterly irresponsible.
