“I came to cast fire on the earth, and would that it were already kindled! I have a baptism to be baptized with, and how great is my distress until it is accomplished! Do you think that I have come to give peace on earth? No, I tell you, but rather division.” — Jesus
It is a fact of history and of psychology that people kill and will die for faith. Whether this is seen as devotion or extremism depends on who is doing the killing and who is doing the dying. It is one thing to die because of one’s faith; it is another thing to kill for one’s faith. What drives people to this? And does extremism hold logically?
