Was Jesus' sacrifice really a sacrifice at all?

albeit smaller than what thousands of his contempoaries whom the Romans crucified

Later xtian propaganda. It appears, despite later forgeries, that the Romans took no notice of them until the mid-3'd century when they finally became numerous enough to notice. It was also a bad time for the Roman empire, with a string of serious defeats in the East, and xtians gloating about the coming of a 'new kingdom' would have been seen as disloyalty.

No, I ma not talking about Xtians. The Romans cruicified people that annoy them routinely. They crucified 6000 of Spartacus's followers in one go. They also crucified thousands during the 68 AD Jewish revolt. It's Xtain propaganda that there was anything special about it. Before the Romans the Phoenicians and Itruscans also crucified people. The deranged preacher did not suffer more than is usual for people held in low regard by the Romans. Romans also crucified other religious malcontents and annoying preachers. The same Tiberius in whose reign Jesus supposedly died also ordered the priestess of Isis in Rome crucified for spreading a cult not met with Imperial approval.
