Do the Catholics consider Orthodox Christians heretics? The Orthodox Christians consider Catholics heretics. But what is the opposite case?
No.  Perhaps the best statement of the current Roman Catholic position on the schism can be found in Unitatis Redintegratio from Vatican II.  Essentially, the Roman Catholic Church holds that the doctrinal issues that exist are minor if not meaningless, and often result as different ways of expressing or experiencing the same understanding of God rather than from a fundamentally different understanding of God in the first place; from the Catholic perspective, the split is primarily over matters of church organization and not theology.

For an example, consider the filioque: from the Catholic perspective, the difference between the single and double procession is a matter of choice of emphasis rather than of basically different belief.  Tellingly, the Roman church does not require Eastern-Rite Catholic churches to use it.
