In such a situation, the second things get dangerous, no hesitation. Fight or flight. If you will fight, go for the knockout punch without a second to even think about it. Prepare your mind if you must. If your friend has been dropped, this is the natural thing to do. You don't leave your friend. Unless they pull a knife or something, in which case I would run. Unless it is my brother or something, in which case you make distance and find an object, hold them off, and make a major commotion.
Yeah, that sounds bad. But if a guy pulls a knife, they are threatening you specifically. It would take an absolute psycho to go on and slit your KO'd friend's throat once you have run away. In fact, if you have a chance and someone pulls a knife, getting the f u ck out, and getting on your cellphone to the cops at the absolute soonest possible second is probably the best option.
But if it is someone like your brother, or for that matter your girlfriend, or god forbid your wife, etc., you will do everything you can to fight.
