Why did Jesus have to die on the cross, sacrifice for us?

We know it was for our sins, but:
– Why did our sins require the sacrifice of God himself?
– And they demanded it? Or would it go without it?
– Then why the sacrifice of God – why the cross?
It would be our salvation (deification) maybe without it?
First:
For what Jesus did for sure
DON’T BECOME! * Redeem – pay for something to be redeemed. Used in the sense of redemption from captivity, when someone paid a ransom for the prisoner and the prisoner was released. In this sense, Jesus is called the Redeemer, and we are called the redeemed.
Ransom from Satan: This opinion looks at the atonement of Christ, as for ransom that was paid to Satan to man was bought freedom and to be liberated from Satan enslavement. Substitute punishment theory:
This theory looks at Christ’s reconciliation as for substitute victim who satisfied God’s demands on sin. His victim Christ paid the punishment of human sin; he brought forgiveness, he established
justice and reconciliation, a man with God.

There are many theories and speculations as to why God as a man, Jesus Christ, had to make a sacrifice on the cross – and to whom as the Redeemer * paid.
The two most common – present since ancient times – are the following: • REDEMPTION DEVIL: We have sinned rightfully
owned, owned by the Devil, and we belonged to Hell. To us so, Jesus saved the Devil from power and redeemed himself from Hell, paid for us Satan’s proper price to himself, his Blood… Finally, he escaped the Devil, so the Devil (as if deceived by God) came out empty: without sinners and Christ as a ransom.
• REDEMPTION TO GODFATHER: God as infinite justice had to insist on a just – and therefore infinitely large – punishing a man for an infinitely great insult to the infinite God, which is the sin of man (even the smallest because of the greatness of insult is measured by the size of the offended, in this case, infinite God) caused. So to save a man, he left it. Instead, the man has punished His Son, Jesus Christ… To whom, and why was it for is paid over blood? If the devil – what shameful! The thief accepts ransom, not only from God, but the ransom to whom is God Himself!
Does God pay the ransom to the Devil?
But this raises several questions:
• Does this mean that Satan is more powerful than God?
• It means that God must “pay the tax” to the Devil to deliver
man?
• So the devil wasn’t really defeated at all, and in the end, you did
he enforced his against God – and did God have to pay?
• It is right and moral to pay a ransom to a thief – like the Devil
called St. Gregor Naziánus
• And if Jesus paid Satan himself – then he is God
since the possession of Satan?
• And if Jesus did not remain in Satan’s power but “overcame him,” is
such ransom valid? And honest ☺ né Worthy of a Holy God?
• And if God does have enough power to be on the Devil enforced his – and then the theater with the “ransom” that he The “infinite satisfaction” that God seems to insist on these gets into double the annoying light. From the texts of many devotions, it is printed to the consciousness of the idea that the Christian faith in the cross imagines God, whose reckless justice requires human sacrifice, even one’s own sacrifice Son. From justice, whose dark anger makes a message of love unbelievable, a man turns away in horror. This image is just as widespread as incorrect. ” (Joseph Ratzinger – Benedict XVI)

However, if this price was offered to the Father, I ask how would that be possible? After all, it wasn’t the Father who kept us captive! An as if Blood of your own beloved Son could be pleasing to the Father who he didn’t even accept it the sacrifice of Isaac when He gave Him Abraham offered as a full victim but replaced human sacrifice lamb.
-Does God pay a ransom to God?
This also raises several questions:
• It means, however, that forgiving and not persevering is, therefore,
injustice – and therefore sin? Shouldn’t we do it?
• But then why does Jesus ask us to?
• And punish the innocent instead of the culprit – is that fair?
• And since Christ Jesus, Himself is God (and when He became man,
did not cease to be God) – it means that God sacrifices himself, he suffers to meet his demand to be somehow (by himself!) “compensated” for insults by people? But if he did not pay to God,
