genocide is considered among the special breeds of "universal evil", a crime against life itself.. mass genocide even moreso.. while it is sadly common among terroristic groups / factions it is still worth noting even hardened criminals often think of mass genocide as pretty disgusting (the killing of women and children especially).

so in general genocidal villains are at minimum borderline PE, this one takes it a step further so is well within PE alignment.
