As a vegetarian, eating meat really isn’t amongst the worst things I do in Minecraft. If you think about the way an iron farm functions, you repeatedly scare a villager so that iron golems spawn, which you than kill. To even be able to start a new village you first have to kidnap a few villagers(unless you want to do the zombie curing thing). Oh while we are at it, if you want cheap prices with the villagers, you can trauma bond them to yourself, by repeatedly letting them get killed by zombies and curing them again. Villagers are also the only way to automatically farm crops so I have one trapped on a farm with a minecart under it as well. :>
