The fault should be blamed on law, which is connected to the tree of knowledge of good and evil. Jesus, who was a Jew through his mother, Mary, taught a new doctrine of love and faith that applied to all people and not just the Jews. This new doctrine was against the Old Testament Jewish Law. Jesus was claiming he was the Son of God and the Messiah, which were mortal sins in the eyes of the Jewish law.
What Jesus taught was not against Roman Law. Rome had a policy of allowing its conquered countries to retain traditions; cultural and religious freedom. Rome was not insecure in that sense, and they found it easier to manage their vast empire of cultures this way, since it showed compassion for deeply felt beliefs; states rights, but with Federal controls. If they needed armies they were easier to raise.
The law that Jesus broke, that got this all going, was Jewish law, which the Jewish leaders felt, qualified as heresy. The wage of this terrible sin was death. The Jewish leaders became the judge and jury based on their scholarly knowledge of their law. However, they could not act, since this would be against Roman Law; cause internal problems. They pressured Pilot to take acton on their behalf, since Rome did not allow internal squabbles and Civil Wars.
Rome, as represented by Pilot, saw nothing wrong in the original legal picture, in terms of Roman law. However, his job, as a Roman Governor and Roman Bureaucrat was to maintain peace and order. Pilot went along to appease the noisiest crowd, so he could end the instability, less he be thought to be incompetent and replaced. Pilot was looking out for his own career and did not wish to violate the Roman laws of empire Bureaucracy.
Since all forms of law began with Satan in the tree of knowledge of good and evil, Satan and those who worshiped him, via laws of right and wrong, were all responsible. Sin and punishment would not have been imputed to Jesus, if there had been no law against Jesus's free speech teachings. But instead of free speech and debate, these legal system set up legal censorship, by self serving truth detectors, based on their own self interests; Democrats Party rules and Twitter censorship to kill accounts.
The analogy is, say it was deemed to be against the law to be a witch. The self righteous may decide it is good to round up, torture and even kill those accused of being witches. They are doing good by their law by rounding up this terrible evil. However, none off this is an objective good, since their law is subjective and self serving. Law is too easy to twist and distort for personal gain. Every evil dictator will use laws designed to maintain their power.
There is no such things as fairly tale witches, but a law was created based on imaginary enemies that need to be stopped. This law then justifies cruel behavior by the mob, since if you do not act, you will be charged with condoning witchery and then pursued as a minion of the fairy tale witches. This would happened to the followers of Jesus. Their peaceful protests against the objective cruelty, after the fact, caused Roman law of order to be broken, so they now had to be rounded up.
Hitler, in WWII, would use law against the Jews. Before Hitler was fully in power, he had sent lawyers to the USA to learn from the American Democrat party; south will rise again, how to make and use law to create an entire race of second class citizens; blacks, with limited rights.
When these Lawyers, returned to Germany, it became unlawful to be a Jew; witch and bogeyman. This was subjective law, but it was still the law, since it was strictly enforced by those in power with all the might. People had to go along, to get along, to avoid the foot of the law stomping on them. Law is easily is often misused and causes so much death and pain. This is why Jesus went after law, and did away with law of all types. The righteous man needed to live by faith apart from law; unique judgement for any situation instead of one size fits all.
When Jesus was killed and resurrected, this tragedy had been part of a larger master strategy. The ultimate penalty for breaking the strongest of laws; subjective or objective, is the death penalty. Once you are dead, you can no longer break any laws, since you are dead and not animated to do anything. Death separates one from law and all its requirements.
When Jesus died and was resurrected he came back as someone who was now outside the law; double jeopardy. The resurrection, which which nobody expected, created as loophole that neutralized law at the level of heaven. This loophole would lead to a war in heaven where Satan and his followers; 1/3 of the angels, were expelled; Revelations, with Jesus taking over Satan's heavenly job as a mediator to humans, at the right hand of God. Law would no longer be condoned by God.
However, with Satan driven to the Earth and not condoned by heaven, as had been the case in the Old Testament, Satan and man, via law, would bump up their cruelty, via law. One complaint by the Atheists, about the Catholic Church, is based on the laws that would be imposed over the centuries. Law does not have to be rational to create social dynamics that can lead to death and suffering. law was still thought to be divine and from God, even though Satan no longer in Heaven, sold as the divine rights of kings; laws of man.
