So on this wiki the Freudian concept of the Id and the character archetype of the Mc Coy are meant to be one and the same, however as far as I can make out, the Id is driven by animal impulses and amoral, often self-interested desires, while the Mc Coy is meant to be more compassionate and humanistic. Both are driven by irrational impulses, but the Id is more self-serving while the Mc Coy is more concerned with what is "right" and individuals, thus it seems to me that they are not synonymous.
