I'll add this to the OP.

A completely random person will die. If you kill someone it doesn't count. You will be hunted and stabbed to death by a murderer. The person who dies gets no money.  Not even for his family. 

Would you still play if it's known the next contestant is a member of thay guys family?

Do you get to fight back? Because I think I could take a murderer with a knife. And if you beat him does he go after someone else? Or do you get to kill the murderer in self defense and collect the 10m?

I agree. I mean I have guns... A guy weilding a knife isn't all that frightning.

I would probably select a priest or nun, so no worries. 

Wouldnt be very random if you get to choose the person yourself.

No its a game like similar to the film final destination.  Once you're chosen you will die soon no matter what you do. 

Yeah, I don't think a priest or nun would sign up to win 10 mil. They aren't supposed to have worldly possessions and all.

You said I get to point out a person. Either way I'd still do it, people die everyday, what one more going to hurt? Well as long as that didn't include children, even though I can't stand kids, I would feel some guilt in that situation. #Misanthrope 

I think that's what the reality show would want to achieve. Make every player feel scared of each other and see who falls to insanity the fastest until he/she becomes the murderer.
