Assuming you mean by that that you don't believe in it, you've cleanly discarded Christianity itself.
Without original sin, some people can get to heaven without Jesus. If some people can get to heaven without Jesus, the next apostasy is to assert that all people can get to heaven without Jesus. The next apostasy after that is to assert that Jesus was nobody special.
Yet your rejection of original sin, which makes Protestantism, Catholicism, and to a great degree Orthodoxy into dead letters, will earn no condemnation from the anti-Catholic crowd here.
Romans 5:12-14 NASB
No, that does not follow. It is often repeated in Scripture that one is not condemned due to what they are not culpable for, (Deuteronomy 24:16; 2Ki 14:5,6; 2Ch 25:4; Jer 31:29,30; Eze 18:20) Also in the judgement seat of Christ believers will be accountable for "the things done in his body," according to that he hath done, whether it be good or bad." (2 Corinthians 5:10)
Moreover, the stated requirement for baptism is penitent whole-hearted faith, (Acts 2:38; 8:36,37) which the morally in cognizant cannot and need not choose to do, as they are not culpable of sin.
Yet this does not translate into some people getting to heaven without Jesus, which is impossible, (Jn. 14:6; Acts 4:12) but with God all things are, and if the Lord Jesus prayed "Father, forgive them; for they know not what they do," (Luke 23:34) though in this case they made cognizant moral choices, though ignorant of them being evil, so also on His account the Lord can obtain acceptance of morally incognizant innocent souls, even of those aborted who could not be baptized.
That at least, is how I see it can happen. To the glory of God.
