The Id, of course, is our most basic primal instincts (hunger, thirst, self-preservation, and pleasure drives) it wants what it what it wants when it wants it, and operates on the pleasure principal (if it feels good, do it.) which made me think of the Chaotic Neutral alignment.
From Wikipedia:
"Chaotic Neutral is called the "Anarchist" or "Free Spirit" alignment. A character of this alignment is an individualist who follows his or her own heart, and generally shirks rules and traditions. Good and Evil come a distant second to their need for personal freedom, and the only reliable thing about them is how totally unreliable they are. They typically act out of self-interest, but do not specifically enjoy seeing others suffer. Many free-spirited adventurers are of this alignment. Alternatively there are madmen whose actions are chaotic, but are not themselves inclined towards evil. A good example of this is Captain Jack Sparrow."
The Ego, is of course, the self, our conscious thinking being, operating on the reality principal, it seeks to satisfy the demands of the Id only when negative concequences do not result (the reality principal). This makes me think of the Lawful Evil alignment.
From Wikipedia:
"Lawful Evil is referred to as the "Dominator" or "Diabolic" alignment. Characters of this alignment see a well-ordered system as being easier to exploit, and show a combination of desirable and undesirable traits; while they usually obey their superiors and keep their word, they care nothing for the rights and freedoms of other individuals. Examples of this alignment include tyrants, devils, undiscriminating mercenary types who have a strict code of conduct, and loyal soldiers who enjoy the act of killing.
Like Lawful Good Paladins, Lawful Evil characters may sometimes find themselves faced with the dilemma of whether to obey law or evil when the two conflict - however their issues with Law versus Evil are more concerned with "Will I get caught?" vs "How does this benefit me?" Think Boba Fett, of Star Wars, or perhaps Magneto of the X-Men."
Then there is the Super Ego, a moral compass of sorts. This is where our conscience comes from. Making me think of the Lawful Good Alignment.
From Wikipedia:
"Lawful Good is known as the "Saintly" or "Crusader" alignment. A Lawful Good character typically acts with compassion, and always with honor and a sense of duty. Lawful Good characters, especially paladins, may sometimes find themselves faced with the dilemma of whether to obey law or good when the two conflict - for example, upholding a sworn oath when it would lead innocents to come to harm - or conflicts between two orders, such as between their religious law and the law of the local ruler. Think something along the lines of Dick Tracy, Indiana Jones, or Batman."
