@StrykerxS77x Then that part of Monsters faction characters, which may be capable of understanding moral principles, are they really intentionally evil?
Are Cyclops evil or are they just defending their territory? Are ghouls evil or are they just acting on their instincts (lower neural activity) rather than thinking (higher neural activity). Moral principles are definitely related to higher neural activity.
Are criminals evil or are they just trying to survive? Perhaps their bad upbringing is to blame for their current attitudes.
