You have a different reputation in every village in Minecraft. It ranges from -30 to +30, starting at 0. Your reputation can be increased by trading with villagers and upgrading their professional skills. If you attack or kill a villager or their baby, your reputation will drop. Therefore, if your village is full, don’t kill anyone – instead, send them away. When it drops below -15, villagers become hostile to you and iron golems attack you, so trading becomes nearly impossible. Furthermore, if you kill an iron golem, your reputation drops by another 10 points, so getting rid of them won’t solve the problem. Villagers also gossip, affecting your reputation. Breeding villagers doesn’t increase your reputation, but when a baby villager grows up, you can make them an apprentice to get additional reputation points.
