How is it that the Roman guards would permit this? Would they have turned a blind eye, as modern LEOs often do? Or have the Romans been given worse press than they actually deserved? Or it's possible they didn't have, at the time, a good grasp on when death occurs. A person could be alive, yet taken for dead.
In my opinion, if he was a messenger from God, or a jivanmukta, I cannot see how God would "sell him out" and permit such an ignoble death. To that end, I can see him surviving the crucifixion, if it was he who was crucified, and not someone else.
Pilate ,the Roman official did not see any offence of Jesus and wanted to let Jesus go free but the Jews threatened him; so he sort of found a way to free with an underhand dealing .
It seems that Guards were also bribed by Jesus' friends who took his body, in my opinion.
"Mirza Ghulam Ahmad, the Promised Messiah 1835-1908 Says:
In short, these gospels contain many things which show that they have not preserved their original form, or that their writers were some other persons not the disciples. For example, can the statement of the gospel according to Matthew: And this is well known among the Jews till to-day, be properly ascribed to Matthew? Does it not show that the writer of the gospel of Matthew was some other person who lived at a time when Matthew had already died? Then, the same gospel of Matthew 28:12,13 says: And they were assembled with the elders, and had taken counsel, they gave large money unto the soldiers, saying, Say ye, his disciples came by night and stole him away while we slept.
It would be noticed how unconvincing and irrational such statements are. If the meaning of this statement is that the Jews wanted to conceal the rising of Jesus from the dead, and that they had bribed the soldiers in order that this great miracle should not become generally known, why was it that Jesus, whose duty it was to proclaim this miracle among the Jews, kept it a secret; nay, he forbade even others to disclose it? If it is urged that he was afraid of being caught, I would say, that when the decree of God had descended upon him, and he had, after suffering death, come to life again, assuming a spiritual and a glorious body, what fear did he now have of the Jews surely the Jews now had no power over him; he was now beyond and above mortal existence?
One observes with regret that while, on the one hand, it is said that he was made to live again and assume a spiritual body, that he met the disciples and went to Galilee and thence went to heaven, he is nevertheless afraid of the Jews for quite trivial things and, in spite of his glorious body, he fled secretly from the country, lest the Jews discover him; he made a journey of seventy miles to Galilee in order to save his life and time and again asked the people not to mention this to others.
Are these the signs and ways of a glorious body? No, the truth is that it was not a new and a glorious body it was the same body, with wounds on it, which had been saved from death; and, as there was still the fear of the Jews, Jesus, making use of all precautions, left the land. All talk of anything contrary to this is absurd as the one about the Jews having bribed the soldiers in order to make them say that the disciples had stolen the corpse while they (the soldiers) were asleep. If the soldiers were asleep they could be very well asked how they came to know in their sleep that the corpse of Jesus had been stolen away. From the mere fact of Jesus not being in the tomb, can anybody in reason believe that he had gone up to heaven?
Jesus in India
Furthermore, in the Greek version of the Gospels, when Joseph of Arimetha asks for Jesus' body, he used the word soma -- a word applied only to a living body. Pilate, assenting to the request, employs the word ptoma -- which means "corpse". (Perhaps the Greeks knew something we didn't.) Interestingly, there is also the possibility that Pilate was bribed. This would account for the crucifiction taking place at the Garden of Gethsemane (private land), and for the body being taken down so quickly. In short the evidence is overwhelming that the Cruci- fixion was instead a Cruci- fiction.
The Crucifiction
At best, neither the story of an accusation of theft nor that of guards is more likely to be true than the other. But even if we assume a guard, the gospel also depicts these guards as accepting a bribe to lie about theft, and thus it follows that the guards would be just as likely to accept a bribe to allow Jesus to escape. Indeed, they would probably have no qualms about accepting both bribes, being twice the richer for it. And since Jesus was placed in the tomb of his rich and influential supporter, Joseph of Arimathea, there is a strong possibility of bribery.
