Of course, having a conversation like that with a JW will yield little more than a convoluted, rationalized response. A believer is incapable of applying logic in the same manner to their beliefs, as they do in other areas of their lives. Intelligence and critical thinking are compartmentalized.
Yes, JWs are both fundamentalist, (as they choose to take much of their particular ancient writings literally), which only could follow that they are fanatical. They very idea of taking such ancient writings literally whole or in part, is fanatical in of itself.
JWs don't have to kill to be fanatics. They believe their god will do that for them, which is just as evil by proxy.
