Everyone agrees that Don John is evil. But some say he should interfere in the marriage of Claudio and Hero and others say he should not. Don John should not interfere with Claudio and Hero’s marriage for three reasons: It is selfish, he will face his brother's wrath, and it is wrong. The first reason that Don John should not interfere with Claudio and Hero’s marriage is that it is
selfish. Don John selfishly entices Borachio and Conrade into his evil plan to destroy the marriage. He convinces Borachio to make it seem that him and Margaret are Hero and another man while Don John shows the scene to Claudio and Don Pedro for a measly one thousand ducats. Then he selfishly flees Messina leaving Borachio and Conrade to serve punishment for his evil plan. Don John thinks only of himself and his pleasure when he conceives the plan and only carries it out for the purpose of pleasure. The Second reason that Don John should not interfere with Claudio and Hero’s marriage is that he will have his brother’s wrath. Don John’s brother, Don Pedro, cares for Hero and Claudio (his right hand man) and gladly agreed to help Claudio woo Hero. If Don John undoes all of Don Pedro’s hard work Don Pedro will be exceedingly angry and may initiate serious consequences for Don John. In exchange for the compassion that Don Pedro showed to Don John, by letting Don John join Don Pedro’s army, Don Pedro receives an act of criminality against his best friend and right hand man. The third reason that Don John should not interfere with Claudio and Hero’s marriage is that it is wrong. It is deceitful of Don John to do this against Don Pedro, Leonato, Claudio, and Hero. Don John shows jealousy by interfering in the marriage by selfishly thinking of his own pleasure and gain from the destruction of the marriage. Don John should not interfere with Claudio and Hero’s marriage because it is selfish, he will face his brother's wrath, and it is wrong. All men cares that Don John does not interfere in the marriage because they do not want their evil twins interfering in their marriage.
