Sins can only be forgiven with repentance - this presumption that Jesus 'Lamb' died for the sins is contrary to Jesus teachings and only appears in Johns Gospel - long time after and arguably corrupted.
Matthew 9:13 - 13 But go and learn what this means: I desire mercy, not sacrifice For I have not come to call the righteous, but sinners.”
First for the OP! Read your verse in context! And use a modern version so you can understand what the passage says. Another theological error made by someone who doesn't understand KJV English!

"for all have sinned and fall short of the glory of God, 24 and all are justified freely by his grace through the redemption that came by Christ Jesus. 25 God presented Christ as a sacrifice of atonement, through the shedding of his blood—to be received by faith. He did this to demonstrate his righteousness, because in his forbearance he had left the sins committed beforehand unpunished—" Roman's 3:23b-25
Christ was the sacrifice for sin! That is our redemption! I do accept Paul's words, because they have proved to be correct over the last 2000 years. You have created a piece of theology, not based on taking out (exegesis) of the Bible. But, instead, by taking your theory and reading it into the Bible- eisegesis! Bad hermeneutics or Bible interpretation!
John 3:17 says, “God did not send the Son into the world to condemn the world, but in order that the world might be saved through him.” By sacrificing himself for us on the cross, he took the punishment for all of our sins at once.
"For Christ did not send me to baptize, but to preach the gospel, not with cleverness of speech, so that the cross of Christ would not be made of no effect.
18 For the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God." 1 Cor. 1:17-18
"But far be it from me to boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world." Gal 6:14
"His purpose was to create in himself one new humanity out of the two, thus making peace, 16 and in one body to reconcile both of them to God through the cross, by which he put to death their hostility." Eph 2:15b- 16
"For God was pleased to have all his fullness dwell in him, 20 and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross." Col 1:19b-20
"When you were dead in your sins and in the uncircumcision of your flesh, God made you alive with Christ. He forgave us all our sins, 14 having canceled the charge of our legal indebtedness, which stood against us and condemned us; he has taken it away, nailing it to the cross. 15 And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross." Col 2:13-15
"He himself bore our sins” in his body on the cross, so that we might die to sins and live for righteousness; “by his wounds you have been healed.” 1 Peter 2:24
So many places in the Bible, including one of Jesus' disciples who walked with Christ for 3 years, saying we are redeemed through the cross. There are more, but the collections of verses & passages, condemns your weird alternative, of making Jesus into what you want to see, rather than what is faithfully recorded in the Bible!
I often say what a great study in theology the cross makes!
