The Illagers are truely ill, things like vindicators are literally insane, but how? Perhaps if villagers are in a light level of seven or less for 10 or 15 in game days then they become insane, turning into something like a vindicator. This would make people want to properly take care of villagers instead of treating them with poor conditions. Now you may be wondering whow do u keep my villagers from becoming insane? Well as long as your villagers are in a light level above 7 then your villagers will be fine and dandy!!!
