Can you prove that God is just for punishing Jesus without taking into account Jesus also being God?

If Jesus was merely a man, then God would seem unjust for punishing the innocent Jesus in place of the guilty due to violating the following: 1. Man is to be put to death for his own sin and not for the sin of another (Ez 18:20; Dt 24:16) 2. No man can ransom another or give to God the price of his life (Ps 49:7-9) Moreover, God seems unjust for WANTING to crush the innocent man that is Jesus (Is 53:10; Lk 22:42), regardless of Jesus' willingness to follow the Father's will and lay His life down as a sacrifice. That God could desire and plan to punish/sacrifice an innocent man, His Son no less, for the sins of others would go against His character. The only way I see God being just would be that Jesus is God. Thus, God's plan would not be the unjust sacrifice of an innocent third party but rather the just, noble sacrifice of the self. But if you can show that God is just in sacrificing Jesus even if Jesus isn't God, then please leave an answer down below.
