My one fatal flaw to this whole idea was so what. Almost everyone wanted the man dead except for the Mr. and Mrs. Romanov. He was incredibly influential crazy man who scared everyone.
If this really bothers people I think ignorance will help you to sleep at night because I am sure this happens MUCH more than anyone cares to figure.
Plus we wouldn't have the most amazing story of how Rasputin died. That story scares me every time I read it. Shot, poisoned enough to kill a person multiple of times over and he dies from drowning when they threw his body over into the river inside a rug.
