Jealousy and Death

Ernest Johnes says that one's jealousy will arise one's desire to remove rivals. Assume Hamlet desired all of his mother's affection in his childhood, but his father took away much more love from his mother. Thus, his father is his first rival. If his father was not posined by his uncle, the tragic of Hamlet would be as similar as Oedipus' killed his father and slept with his mother. This theory is respectful, but in fact normal people don't behave like that.
