While God was in charge in the first 2 chapters of Gn., everything was very good. There were "growing pains" as a nascent  population discovered the phenomena of an evolving world, but those were part of creation, not punishment.

When Adam and Eve became stewards in Gn. 3, humanity not only became aware of pain. Humans became agents of pain. Humanity began to use intellect and free will for domination not unification. This is not God's will. This was, and continues being, humanity's choice.

Jesus did not come to do away with pain. He came to show us how to pray, "Our Father, thy will be done," and to remind us how this is accomplished, "Do to others whatever you would have them do to you." (Mt. 5-7)

"Growing pains" are natural, and our human family has the competence and capacity to deal with them. Pain caused by humans is humanity's dilemma. Abel and Jesus experienced and survived "growing pains." It was human agents that caused their fatal pain.

The choice is still ours.
