Morals; are there any?

It makes sense that Shakespeare would include morals in his plays. Especially this play. As Gamze wrote earlier, Othello was developed from a story in Cinthio's (Giraldi Cinzio) collection, the Hecatommithi, which it follows closely. Cinthio drew a moral in his story, (which he placed in the mouth of the lady), that European women are unwise to marry the temperamental males of other nations. Now, if most of the other aspects of Shakespeares and Cinthio's plays are similar, why do they not both have morals. What morals could 'Othello' be supposed to portray? That inter-racial marriages 'can never be'? Remember in those days, this was frowned upon and that is why Brabantio was so irate. Can you think of any others? This could help with the coursework on 'fate'. Othello included morals so 'Othello had to fall from grace'?

Any ideas would be great!

Thanks all,
