The Cataylist says quite clearly "They are my solution" He explained the purpose of the Reapers and gave you a way to destroy or control them. Were you even listening when he Cataylist came on because its seems pretty obvious he made them. It also mentioned "we control him" refering to indoctrinated TIM, so he considers the Reapers and him the same.
