Methods PArt 1- imperfect

"But because being decieved and being mistaken appear to be a certain imperfection, the less powerful they take the author of my origin to be, the more probable it will be that I am so imperfect that I am always decieved." This strong quote by Descartes left me kind of confused. Is descartes out and out challenging the idea of God here? Is he mad at God for bestowing him imperfect and misunderstood? Or is he pointing out how imperfect God really is in his creation of human? Perhaps maybe he is just stating that what is thought of as imperfect has too much weight on the silly petty things. Everyone is decieved at some point, whether it be from someone superior or of authority, or from a sense or thought, or a pet dog??... Maybe too much thought is put into how each individual is wrong for some reason or another, maybe God wanted his creations to be slightly imperfect each in their own way? Or mayb God just has not yet mastered the makings of humans, which is why we are all at fault and imperfect...
