What you fail to understand is that it is God who killed the Lord Jesus. Mark 14:27, quoting Zechariah 13:7. 'For it is written, "I will strike the Shepherd."' Isaiah 53:10. 'Yet it pleased the LORD to bruise Him. He has put Him to grief.' I hope we can agree that whatever God does is just, and therefore the Lord Jesus was not unjustly killed. Wicked men killed Him without a cause, but they were doing exactly what God had decided should be done (Acts of the Apostles 4:27-28). The explanation for this is probably best expressed in Genesis 50:20. 'You [i.e. Jewish leaders, Herod, Pilate, Roman soldiers] meant evil against Me, but God meant it for good, in order to bring it about as it is this day, to save many people alive.' I can conceive of nothing more wonderful than this: that God Himself, in the Person of Jesus Christ, should willingly suffer instead of us the death, punishment and curse due to fallen mankind as the penalty for sin so that God might be just and the justifier of the one who believes in Jesus (Romans 3:26).
God ordains events in which injustices and sins take place without Himself being unjust or authoring sin.
Statements of God "striking" and "bruising" Jesus are not sufficient to show that God is justly punishing him. See places like Psalm 44.
We have not dealt falsely with Your covenant.
Our heart has not turned back,
And our steps have not deviated from Your way,
Yet You have crushed us in a place of jackals
And covered us with the shadow of death.
The language of God "crushing" and "covering with the shadow of death" is used of those who are innocent and unjustly suffering.
God "crushed" and "struck" Jesus in the same way he struck Abel, Stephen the Martyr, Joseph (your own example), Naboth, etc.
He "struck" them by ordaining that they would be unjustly killed. The writer of Hebrews says that we have been brought near to "Jesus, the mediator of a new covenant, and to the sprinkled blood, which speaks better than the blood of Abel. (Hebrews 12)" The blood of the covenant which has been shed is the blood of an innocent person who has been unjustly murdered, like Abel except better than Abel. Peter says that we were purchased with "with precious blood, as of a lamb unblemished and spotless, the blood of Christ(1 Peter 1)" not guilty blood shed by just punishment or vengeance. All the emphasis is on the innocence and purity of the blood.
Only innocent deaths merit the reversal of death, and only Jesus can be the truly innocent party.
I can conceive of nothing more wonderful than this: that God Himself, in the Person of Jesus Christ, should willingly suffer instead of us the death, punishment and curse due to fallen mankind as the penalty for sin so that God might be just and the justifier of the one who believes in Jesus (Romans 3:26)
I can conceive of something far more wonderful than that: the atonement that is actually in the Bible. The one that includes Jesus rising from the dead, which is nowhere in your post. That I was dead in my transgressions and sins, already a child of wrath (Eph 2). But Jesus was crucified so that I could be co-crucified with him (Gal 2). Though we were under the same sentence of condemnation and mine was just, his was unjust (Luke 23). Justice demanded the reversal of his unjust death, "The justice due to him was with God" (Isaiah 49:4) and he rose from death so that I could be raised with him, for he was "raised for our justification" (Romans 4).
