There have been few methods of execution more excruciatingly painful than crucifixion, and the Romans mastered it.
By design, death on a cross was not quick. Soldiers would first whip the victim with a scourge and then force him to carry his own crossbeam to the execution site. Once suspended on a cross, the hours in a strained position took
a toll, causing difficulty in breathing and often resulting in suffocation. Some victims would hang alive for days, finally succumbing to death as a welcome relief.
