a new menu for iron golem

Iron golems are a beatuful mob but used more for decoration in worlds. It could effectively make a pet that maybe you can't carry around but let it defend. It could be used in articular in servers where you could put through the golem menù, an example and tell it to kill the players that approach or with some plaugin that kill the enemy faction, or beat the players who rummage in the chests giving a depth major to game and the last could be to kill all ostile and neutrall mobs (so in case someone wants to do an automatic farm it can't because here mobs would kill him in the long time) this is my idea. But in any case, to clarify, the menu cannot be opened unless you created it
