You don't understand, Ultron's directive is his Id. To protect the planet. This leads his Ego to formulate a plan that will fufill the Id. That plan is eliminating the biggest threat he found, which was humans based on the info he accessed. Without the Superego to contradict this plan, the Ego would not have to compromise and therefore give into his Id, the directive. So he will fuffil the plan, no matter how flawed so long as he believes he fulfills the Id.
