I dunno if the game really requires one to spend time trying to talk any other player down off the ledge. People do it when they need that person's vote, but just for general harmony, peace and love? Not on a reality TV show.
They certainly do not cast shows for people to get along and calm each other down.
I think the problem is that physical violence is relatively straight forward to put down a line. There can be some fuzziness to the line, but it is fairly easy to define.
Which is worse. Joe putting up a defense when someone is running at him, or the guy screaming in his face to hit him over and over.
Where was Willie's responsibility to disarm the situation by saying "oh I didn't mean to frighten you by running at you" and backing down?
Now I agree Joe wasn't innocent in setting up a volatile situation, but the responsibility for not crossing the line from verbal violence (and lord knows there is more than enough verbal and emotional violence on these shows every day. Most of the "drama" has some element of emotional or verbal violence imbedded in it, IMO) to physical lies with the individual.
The problem is the producers want drama, so you want people who are not going to get along, who are going to yell at each other, make damaging game moves against each other...how do they promote enough not getting along if they ban everyone from ever saying anything that might in anyway upset or inflame a situation? Because really, you never know when calling someone a name or "just messing with them" to throw them off their game is going to push someone over the line to violence. After all it does every day in the real world.
