In the play Hamlet, an external force is the force that influences beyond the control. The external force strongly influences Hamlet to confront his moral belief and value. Hamlet believes that a marriage should not exist between family members who are his uncle and his mother. He believes that if people love one another, they should support and help each other. However, Hamlet cannot get help from Ophelia. Hamlet believes the friendship is important.
At the beginning of the play, Hamlet is very emotional and cheerless. The main reason of being melancholy is his father's, Hamlet Sr.'s sudden death, and the hasty marriage between his mother, Gertrude, and his uncle, Claudius. Hamlet has his own belief that a marriage should not exist between family members. Hamlet shows his anger in his first soliloquy, because this marriage is the one of external forces that compels Hamlet to confront his moral beliefs and values. If this event does not make Hamlet to face his moral beliefs, why Hamlet is so indignant about the marriage? Hamlet says, "By what it fed on, and yet within a month-let me not think on't; frailty, thy name is woman!", and "O God, a beast that wants discourse of reason would have mourn"d longer,-married with my uncle, my father's brother, but no more like my father." Those two speeches show Hamlet's feeling about the marriage. He does not want to believe his mother married his uncle, which he thinks is not right in "his eyes". In addition, he is irate, because Gertrude and Claudius did not take longer than one month to think about the marriage. Did Gertrude and Claudius ever respect Hamlet Sr.? If they respected him even a bit, they would take more than one month to decide. Moreover, did they respect Hamlet? They could have ask Hamlet's permission or what he thought of the marriage. As a result, the hasty marriage compels Hamlet to confront his moral belief.
Hamlet believes if people love one another, they should support and help each other.
