For a start, He would have been hanging there for possibly longer than three hours as he was already dead. Still baking in the sun. Keep in mind He was really brutally whipped before going there which would be enough to kill somebody, as well as staying up for hours, sweating blood long before as well. Crucifixion would have very much killed someone in that state in three hours. Every breath He’d take would cause his back to scrape against the rough wood and cause excruciating (literally) pain. Lastly, His side was pierced and it showed His lungs had collapsed. Then He was buried in a tomb, and guarded by ROMANS, not loyals. In the state He was in, He would have very much died there in the course of three days if He was somehow still alive. Not recovered.

Your last paragraph sounds AI generated lol
