A lot can be determined by the choices we make, even if the action is initiated by self-preservation. Many ... no, most ... of our choices are driven by fear: fear of death, fear of humiliation, fear of loneliness. But it's how we respond to fear that matters. It's what defines us. What makes us who we are. So maybe in your mind you acted selfishly, but I'm alive because of the choice you made. So I'll remember it as an act of kindness and yes, even bravery.
