He and Rasputin are peas in a pod.
He looks like he also tell fortunes and will be poisoned,stabbed,shot,and dumped in a river at some point.
I don't think either of you have any idea what Rasputin actually looked like:

So Moore and he have facial hair, but then so do i and so do a bunch of people. Rasputin looked like any Orthodox cleric you'd care to talk to, it wasn't Rasputin's looks that got him the reputation he had (much of it inaccurate, the only one exhibiting Madness in most famous years of his life was The Tsaritsa Alexandra Fyodorovna).
Moore much more closely resembles Geoffrey Bayldon as Catweazle:
(great show incidentally, good kids books too:) )Or Ian Anderson

And in both of those instances theres a sort of wild man of the woods kind of thing being attempted.
You know who else is often eccentric and looks scary? Psychopaths. Books and covers and all that.
Most people with psychopathy personality disorder wouldn't look like Moore at all. Here are a couple:


Psychopaths are predators, not loons. Hence this book by Robert Hare:

There are tons of psych/sociopaths out there, few of them are criminals, even less look like hairy crazies.
You just don't understand him because he's a genius.
The work of genius is usually pretty easy to understand, I'm not sure what there is about Moore that is supposed to be so hard to understand.
