Iron golems protect villagers. That is their main purpose. So what if a certain villager could care for the golem, this is where my suggestion comes in. What if, say when a golem is hurt? Well if a blacksmith is around (and there program says it's safe) they go to the golem with iron ingots in their hand. It is suggested that the golem is being healed which it is. This method heals 2 health points per second-one whole heart.
