These are Pure Goods who have the ability to give out purposes that are essential and they really need to be kept alive or need to be kept around at every cost. This means that these Pure Goods can't and should never be murdered/ruined because this means something extremely bad will happen. Based on something bad happening if they are killed, they are similar to Necessary Evils but based on their alignment, they are opposites.
