That is what happens when one believes in the doctrines of man, it sinks like the titanic did when its tested.
It's actually way worse than that. Check this out from the history Of Calvinism.
Jacques Gruet, a known opponent of Calvin, was arrested and tortured twice a day for a month in an effort to get him to confess to the accusations against him. Then, on July 26, 1547, he was tied to a stake, his feet were nailed to it, and he was beheaded.
Gruet’s book was later found and burned along with his house while his wife was thrown out into the street to watch. This was not unusual behavior to those who dared to challenge or disagree with Calvin: Gruet was put to the torture many times (444) during many days … In reality such unmeasured use of torture was in Geneva a Calvinistic innovation.
Gruet, refusing under the worst stress of torture to incriminate anyone else, at length, in order to end it, pleaded guilty to the charges against him, praying in his last extremity for a speedy death. On July 26, 1547, his half-dead body was beheaded on the scaffold, the torso being tied and the feet nailed thereto. Such were the judicial methods and mercies of a reformed Christianity, guided by a chief reformer.
Michael Servetus, a scientist, a physician, and theologian was born in Villanova in 1511. He angered Calvin by returning a copy of Calvin’s writings with critical comments in the margins. Calvin drew up a doctrine of over thirty official charges against Servetus, one of which was the rejection of John Calvin’s teaching concerning infant baptism leading to salvation. Five days into the trial, Calvin wrote, “I hope the death sentence will at least be passed upon him.” He also stated regarding Servetus, “If he come, and my influence can avail, I shall not suffer him to depart alive.”
Calvin got his wish on October 27, 1553. Servetus was burned at the stake. He was screaming as he was literally baked alive from the feet upward and suffered the heat of the flames for thirty minutes before finally succumbing to one of the most painful and brutal methods of death possible. Servetus had written a theology book, a copy of which was strapped to the chest of Servetus. The flames from the burning book rose against his face as he screamed in agony.6 While Michael Servetus definitely had some unbiblical teachings, such as his rejection of the Trinity, he was, as the late apologist Dave Hunt puts it, “right about some things: that God does not predestine souls to hell and that God is love.”
Some have tried to say that Calvin was not responsible for the cruel manner in which Servetus was executed and that all he wanted was for Servetus to be beheaded (obviously, a less painful way to be executed). Brenda Nickel, a former Calvinist who was featured in a documentary film about Reformed Theology, provides some insight: Calvin had a long-standing vendetta against Servetus. Servetus foolishly taunted Calvin through letters; thus, Calvin insisted on having him arrested and charged when he entered Geneva. Calvin wanted the death penalty for him.
Servetus pleaded with Calvin to be beheaded instead of being burned at the stake, and Calvin was willing to go along with the idea. If Servetus was beheaded instead of burned, then Calvin couldn’t be blamed. Beheading, in this case, was attractive to both Servetus and Calvin. Beheading would be seen as a civil crime and free Calvin from having blood on his hands. French reformer William Farel rebuked Calvin for the thought. Since the charge was religious and not civil in nature, Servetus was burned at the stake. Melanchthon (Luther’s friend and successor) praised Calvin for Servetus’ death. This execution basically skyrocketed Calvin to fame throughout Europe. It put him on the map, so to speak, as a noteworthy and respected reformer.
Apparently, Calvin must have felt a need to appease himself of guilt in the murders he had helped to institutionalize.
