There is much that could be said about all the rotten fruit that sin produces, but for our purposes, it is enough to recognize that when God laid our iniquities on the Messiah, that action caused more than death. It caused unparalleled agony and disfigurement.
Isaiah 52:14 says that Christ was marred more than any man, such that it was hard to tell He was even human. That is what sin does - it distorts and corrupts the image in which mankind was created. We were created in God's image, but sin destroys that likeness.
