Alignment System

[hamishspence]

It's quite a common trope for the meaner kind of fictional vigilante- Dexter, The Punisher, and so forth- that they torture villains as "punishment for their crimes" yet avoid harming innocents.

Evil people compartmentalise according to Savage Species, treating those they consider "beneath them" brutally while treating their peers and their loved ones with respect.

In this case "peers" is "everyone who is Innocent" and "those they consider beneath them" are "the Guilty".

It isn't just paladins who Fall for evil acts- there's the Holy Liberator PRC, and exalted characters (any character with an exalted feat).

Once the character is "repeatedly, deliberately" committing these evil acts, their Good or Neutral alignment should be called into question.
