How is dishonesty used in the play the othello?

The play's villain, Iago, is the epitome of dishonesty and his untruthful nature is contrasted with the innocent Cassio and Desdemona. He uses his skills in deception to lie to almost every other character in the play  in particular Othello, but also to Roderigo and Cassio.

you can change by someone having a negative opinon of you in many ways for example thi can lead to depression and taking of ones life also known as sucide this effects there self esteem and ego in a negative way making them feel sad depressed and stressed causing them to act gloomy and sad if this continuses this can lead to self harm or much worse things.
