Your right, if you have pride to the point that for instance, I am better then you and you are dirt, then yes, pride is counterproductive to being a good Christian. There is nothing wrong with being prideful. I have pride in serving my country. Does this mean that I am perfect? No. I can never hope to be perfect. If I believe myself to be perfect, then I am diluting myself and having vanity to the point that it would displease my lord. There is nothing in the def of Pride that says to believe ones self to be perfect.
Am I correct to linking that you are trying to link the English def of Pride "to be proud of" to the the seven sins. There is nothing wrong with being proud. I have a son and I am proud of him. Even God was proud of his Son.
Keep in mind that not all def. apply at the same time.
