Actually the Roman's were the ones who allowed it and gave order to do it but in the Bible the Jews are the ones who decided whether he was going to be set free or be crucified. The Romans did not want to specifically kill Jesus Christ as they believed he had not committed a crime worth crucifixion but the Jews wanted him dead. So actually they are the ones who set him to be killed on the cross.

BG ...there you go disrespecting again...
