I think it was more like Big Boss came to see that he and Zero's interpretation of the Boss's will was radically different; whereas Zero became convinced of the necessity of absolute control and was willing to manipulate others to achieve such ends, including soldiers, Big Boss came to believe that the best way to unite the world and make it whole was by creating a way for soldiers across the world to come together to fight without restriction of nationalities, politics, or the times. But as part of his plans to control people, Zero began to experiment with genetic, psychological, and sociological forms of control; researching the differences between nature/nurture, and so stole Big Boss's DNA in order to create Solid and Liquid Snake and research soldier genes. I think Big Boss resented the existence of Solid and Liquid Snake since they weren't natural human beings and refused to acknowledge them. He also probably resented that Zero just used him to further his own ends and betrayed their friendship like that.
