A slight correction. We witness from the quote of our Lord Christ Jesus, that at that moment, Jesus Christ had suffered a spiritual death from God the Father. That death was a consequence of the judgment of all humanity's sins being imputed to Jesus Christ on the Cross. Christ accepted the burden of that imputation and was judged by the Perfect Judgment of the Perfect Righteousness of God the Father.
Once those sins were judged, God the Father was free in His grace to give the human spirit back to Christ via the Holy Spirit and to resurrect the body into the resurrection body as the First Fruits.
Cursed, yes, but this is a different meaning than shamed.
The only shame implied in the Roman and Jewish treatment of our Lord Christ Jesus was based upon a counterfeit substitute to God's Plan in a worldly system of governance.
Even when the mobs spat upon Him, our Lord recognized their sin in judging Him and confusing Him for being sinful by praying to God the Father that He might forgive them for they knew not what they did.
Shame is not like judgement. Judgement flows from an individual in an official sense, while shame is a general sense of reproach and can be formed corporately and amongst a group.
You should not blame the Roman and Jewish authorities for the treatment of our Lord. He did not. He forgave them. Do you realize that what they did, they fulfilled scripture, and that without it, mankind would be lost? Also, Jesus died for OUR sins. It was, in effect the entirety of mankind that crucified Jesus. His blood is on all our hands, just as the guilt of Adams’s sin is on us as well.
