The Puritans were a religious group of early American settlers. ISIS, or Islamic State, ISIL or Daesh, is a militant group of religious extremists in Iraq and Syria. It may seem strange to compare the Puritans to the Islamic State, but both shared religious ideologies that led to horrific atrocities committed in the name of their respective god. Both the Islamic State and the Puritans are groups that use or use their divine status as an excuse to dehumanize, torture and kill innocent people without emotion or regret. This article will show that both groups shared similar behaviors which ultimately led to major atrocities being committed by the groups as a whole and their members. Before continuing, the influence of God can be discussed. It is difficult to reject the action of a god. it's the order. In Puritanism, God's will is absolute. It could be argued that the loving message of the Holy Bible that is taught today is missing from Puritanism. The right to live or die is entirely at God's discretion: "so that Divine Justice may never hinder, he makes no objection to God's using his power at any time to destroy them (Edwards 431 )", and if God puts if it is in you to kill an infidel, what right do you have to question God's will? Followers of Islam confidently argue that it is a religion of love, but the Islamic State's interpretation is a religion of bloodlust. The comparison here is that, while religion itself is not to blame in either case, by perverting the message extremists have taken on the task of being the God-ordained arbiters of who deserves to live or die. We can see the same mentality in Puritanism, where God will “repay the fury of his adversaries” (Edwards 437). In the case of the Islamic State, they are manipulated by the secular military of the Baath Party of Saddam's regime, who don't even care about religion.
