A challenging thought on our understanding of Original Sin.
Man was neither made sinful, nor corrupt, nor was he made for sin or corruption. Man was made incorrupt and for sharing in the incorrupt Life of the All-holy Trinity, now attainable through Christ Jesus.
Sin is not an offense against God; the Lord cannot be offended, insulted, or hurt. Sin is an offense against ourselves, a corruption of our human nature hurtful to us, not to God. The entire purpose of God's moral law is to help us lead the normal life of incorruption, as much as possible in the fallen world, so that our hearts and souls would be open to divine grace and we would rejoice forever abiding in the Glory of God. This is what is normal for human nature; everything that falls short of this, everything that is corrupt, regardless of its origin or composition, is abnormal.
