But if you die trying to save her (we'll use the female in this scenario as an example) and she still gets killed, what good have you done??? I know that some people have the mentality that they can handle anything and blah blah blah, but that way of thinking has gotten many an officer/firefighter/paramedic killed.
Well, if she died anyway, at least she'd die knowing that someone tried to help her. And that's good enough for me.
