What is Iago's Philosophy to Life?

Iago's philosophy to life is that ultimately, we choose who we become. 'Tis in ourselves that we are thus or thus.' [319-320] This quote shows that Iago does not believe in fate. Iago goes on to say that 'If the beam of our life had not one scale of reason, [...] [we'd] conduct most preposterous conclusions. [325-329] This suggests that Iago follows reason more than he does fate as without reason, we'd make incredibly poor decisions. Thus, Iago's philosophy is to follow reason and will. This could be because it allows Iago to justify his actions towards Othello, his reason is to exert revenge and his will is to gain the promotion that he 'deserves'.

I agree with Iago to an extent, while I believe in the basic principles of this philosophy, it too cannot exist without reason or context, it is hard to judge whether a reason is enough to justify our wills. Iago states that he couldn't give a 'fig' to morality as it hinders our progress, but I believe this is not the case as a life without morals would lead to 'preposterous conclusions'. This point can then be seen as contradictory to his philosophy and suggests that Iago is a flawed character.
