In double-entry accounting, each type of account--asset, liability, revenue, expense, and owner's equity--has a normal balance of either debit or credit. Contra accounts are the exception to this rule. Assets normally carry a debit balance but can be reduced by related accounts known as contra assets.
The Snake is the universal symbol of evil. In Harry Potter this archetype holds true. Voldemortâs symbol is the snake and the symbol for Slytherine is also a snake. The students in the Slytherine House are all portrayed/really are, evil (example: Malfoy).
Other character archetypes include the creature of nightmare (Grendel), loyal retainers (Ron and Hermione to Harry Potter) and star-crossed lovers (Romeo and Juliet), and many more. One popular character archetype is the outcast; we see an example of this with Prince Myshkin in Fyodor Dostoyevsky's The Idiot.
