You help because helping is what you do, before anyone has finished asking and long before you have worked out whether it was sensible. That looks like naivety to people who have not thought about it as hard as you have. You considered the alternative, treating every stranger as a threat until proven otherwise, and you decided against it. You are not revisiting that.
