Talk about cherry picking. Weren't you the one that took the position that the guilty should be punished harshly? Well, Jesus was guilty. He was charged, tried, and convicted of two different types of capital crimes in two different courts.Jews helped persecute Jesus.
Jews helped Him be crucified.
According to legend, Jesus spat in the face of both Jewish and Roman law at a time when that was lethal. As a result, he was brought to justice as it was understood and practiced at that time.
I know how tolerant of relative morals Christians can be when defending their god's choices in the Old Testament relative to his later choices concerning topics like genocide, rape, slavery, infanticide, and more. They ask us to accept that things were different then as they explain to us about all new laws reflecting an all new moral code. So, you should have no difficulty accepting the ancient Jews' and Romans' versions of justice.
The Jews helped prosecute Jesus under the laws of the land, not persecute him. Jesus was guilty, and received contemporary justice.
