Othello the Puppet

Othello:  "Yet she must die, else she'll betray more men." (IV.ii.6)

At the beginning of the play, I really liked Othello; he seemed like a really chill guy.  I mean, he was a war hero, and he truly did love Desdemona.  Over the course of the final act, I really lost a lot of respect for the guy.  Let's start with the excerpt mentioned above.  So, let me get this straight: the only way to get a person to stop doing something bad is to kill them?  If the world really ran this way, there would be complete and utter chaos.  Two wrongs do not make a right, but in the mind of Othello, he is always right.  Typical alpha male attitude (strike #1).  Secondly, Othello listens to everything Iago says.  I mean come on!  Does anyone in this play have an independent mind!?  Roderigo, Othello, and Cassio are all manipulated by Iago in some way, shape or form, creating his own puppet show.  The only people who are smart enough to stay away from the man are Desdemona and Emilia, the two women in the play.  I think this shows that the women are the most independent characters in the play sticking to their opinion and standing up for what they think.  Shakespeare may be making a social commentary on his time where women were constantly mistreated.  With this play, Shakespeare defines women as strong, moral people with strong ideas and opinions, the opposite of the view of society.
