A faction that strives to strengthen the community as doctors, vigilantes / law enforcement, farmers, ... so that they have more victims in the community to choose from when they do commit cruelty. Some genuinely believe that the lives they save "make up for" the lives they destroy, others just see it as a clever PR scam, but the innocents who survive the faction's indulgences are legitimately better off then they were before the faction showed up. It's just surviving the faction that makes things tricky.
