Murder mode

When we talking about the FPS, I notice that almost all the server don't like murder mode on. That is a little out of reality -- do you notice how your teammate running around you? They don't care that you are shooting and simply run into the bullets, because we know the damage is zero. But that is not true.

I would like see the mode to turn on the murder mode, I even don't want the friendly flag, here are advantages:
1. a clan need well organized and the closely cooperated;
2. this will make the game more close to reality;
3. we could murder hackers in TDM;

And based on some previous experience, this mode will direct in some murder match in pubs, so we need some enhancement rule:
1. In pub, the murder mode can be turn off;
2. Once murder someone, the murderer will be recorded and if later on the killed is not cheating, you GP will be paid to the death, until all your guns are forced to sold, the experience point will be lost.
3. The murdered number will not be counted into death number, but can be saved to show other player to what extent the player is hated or unorganized.

Also, if someone keeps murdering teammates, he will automatically get kicked before he got bankrupt.

Just for fun
