[Natural Law]

"He doesn't need man's *help* to do it."

No one said anything about need. Jesus' desire is enough.

"Jesus said to them again, “Peace be with you. As the Father has sent me, so I send you.” When he had said this, he breathed on them and said to them, “Receive the Holy Spirit. If you forgive the sins of any, they are forgiven them; if you retain the sins of any, they are retained.” - John 20:21-23

Well then, by Catholic reasoning, since I also have the Holy Spirit in me, then *I* can forgive or retain sins.
