Depraved indifference of the Calvinist

 John Calvin's involvement in the burning of Michael Servetus in 1553 is a controversial aspect of his legacy. While Calvin was a prominent figure in the Reformation, he was also known for his strict enforcement of Calvinist doctrine, which included executing heretics.

• Calvin's authority in Geneva allowed him to condemn Servetus, who was a Unitarian and a heretic at the time. 
• The execution of Servetus was largely due to Calvin's efforts, and it remains a dark mark on his past.
• Sounds like the sort of depraved arsehole who claims KGB Russia is no worse than democratic Ukraine.
