I am utterly amazed that anyone could react negatively to what you did. Would they seriously prefer that you'd left the man to die, rather than tell a little white lie to persuade him to go to hospital? I refuse to believe that anyone hasn't told a lie of similar magnitude at some point in their lives. Hell, I've told far larger whoppers to my daughter just to get her to behave or eat her food or whatever. (e.g. no, a policeman will not come and arrest her if she doesn't stop yelling and running around - and how about the proverbial "if you don't shut up I'll turn the car around"?)
