Even if he did, we would be talking about a hand full of lives, maybe a truckload or two at best along with getting some unwed pussy, man ass, having an illegitimate child, getting VD a few times and turning a few souls away from our lord and savior Jesus Christ. I think Jim Jones had him beat. Compare him to those who have been directly responsible for famines and mass murders ie. Mao, Hitler, or Stalin where deaths were counted in the tens of millions. If he is to be labeled as evil, then it should be evil with a lowercase 'e'. :p
The man wrote fiction and passed it off to the gullible as truth. That's a fucked up thing to do, but it's really not all that uncommon when you really think about it. Religions, cults, governments and rebels do it all the time whether we are talking about using bias to sell things, political propaganda, religious indoctrination, or flat out brainwashing.
