Christian Heaven and Hell

Been having a slight moral crisis lately. If the road to hell is paved with good intentions, can the road to heaven be paved with bad intentions as long as the deeds involved are good? what if both are ambiguous or inconsistent?? what if you try to convince yourself that your intentions are one way but actually they're another though really you may not be sure at all? what if i want to be good but am being self-serving at the same time? what if im just tougher? life is confusing. sigh.
