] Cain and Abel - In Hamlet one brother killed another out of jealousy, only to be exiled and alienated, tormented by his conscience. Seems alot like Claudius, who's also exiled Denmark from "Eden" by his actions, and is tormented with guilt.

If you read back to my post, the part about Claudius likening his own offense to 'the primal curse'--murdering a brother.
