It's a Dangerous WorldFrom Bottom Left to Right
I think Michael had a lot of messages for the world, but had to keep them a little general, obvious and cryptic to you know, not get shot as fast as Lennon or anyone else with a decent message. This cover isn't very cryptic at all but quite out there, but the world is asleep and I never noticed it earlier either...
Between the old elitist pedophile and the hand, there's a world reduced to a Factory that now overshadows the natural world, which ships out Pentagrams, Guns, Skull&Bones, Rockets, an Atomic Symbol (atomic weapons) and a Chemical Formula (bioweapons, or you know, vaccines), etc, all the good stuff!
The other many, many animals on the cover could be alluding to scenes like this perhaps... as Michael is seemingly wearing the Dangerous cover as a mask himself (see youtube vid still or first image).

Michael Jackson: Dangerous
The girl was persuasive The girl I could not trust
The girl was bad The girl was dangerous
I never knew but I was walking the line...
She's so dangerous The girl is dangerous Take away my money Throw away my time You can call me honey But you're no damn good for me
She came at me in sections With the eyes of desire I fell trapped into her Web of sin A touch, a kiss A whisper of love I was at the point of no return
Deep in the darkness of Passion's insanity
I felt taken by lust's Strange inhumanity
The girl is so dangerous I have to pray to God 'Cause I know how Lust can blind
It's a passion in my soul But you're no damn lover friend of mine
And then it happened She touched me
For the lips of A strange woman Drop as a honeycomb
And her mouth was Smoother than oil
But her inner spirit and words were as sharp as A two-edged sword
But I loved it 'Cause it's dangerous
I cannot sleep alone tonight My baby left me here tonight
I cannot cope 'til it's all right
You and your manipulation
You hurt me baby
