Let's look at three similar scenarios: Jim Jones and his cult, David Koresh and his cult and Jesus Christ and his cult.
Upon his death, Jones was responsible for the death of nearly 1000 people, Koresh took around 70 with him and Christ was responsible for the death of thousands of persecuted Christians by the time he grasped a couple of 6 inch nails; not to mention the millions of people who suffered and died in his name afterwards.
Each of these three charismatic charlatans claimed to be the son of God and preached pretty much the same things to their naive, gullible followers. So, how should we judge these self-proclaimed leaders of society?
