Making humanoids make better decisions depending on what the player does.

Everyone knows that even if how many villagers or golems you kill the other villagers will act exactly the same as they did. So why not make them more smarter with some thing that will happen through the game with villagers.

• Small amounts of villagers killed will not really have a big impact on the game, it will only make villagers run away and the golem attack
• Small amounts of village buildings destroyed will make the golem attack and make the villagers mad in a way where they will increase their prices or refuse to trade with you.
• Large amounts of villagers killed should make the golem of that village mad at you for the entire game, villagers of that village won't trade with you or increase their prices by a huge amount.
• Large amounts of village buildings destroyed will make the golem attack, villagers of that village won't trade with you or increase their prices by a huge amount.
• After the golem is killed by the player the villagers will feel threatened by the player. Decreasing their prices when trading, they will also try to stay away from the player. They might also protest by not trading.
• After the golem dies in another way the villagers will try to stay more in their houses.
• Trust level of the villagers will be a feature which determines how much the villagers trust you. The other things i've listed at the top will obviously impact the trust level of the villagers. More trust level means less prices and no chance of them not trading.
