My brother's keeper....

Cain slew Abel, so my Bible says,
And my Bible says,"thou art thy brother's keeper?"
Naughty, naughty me....
How could the Bible, would the Bible see....
what that did mean...to me?
I keep my neighbour- tied in chains, on a leash, in a box,
"So long my pet so long as you don't mind that is, my God says I am your keeper.
And if you mind, well we'll see about that later...won't we?
I decide, if your land, is your own, or if it should rather belong, to the serf who toiled away, on MY soil, a hundred years ago....
I decide, if you ought to protect yourself, from me, and my myriad xenophobic fears of you, and your kin...you who are in my chains, on a leash, in my hand, in MY box....
I decide if an incompetent fool, who lolled along the corridoors of knowledge, a man who was bestowed with education, to deprive you, may play with your ailing heart on a surgeon's table....and if you die...well good riddance...less competition for ME. whoopee!
I decide your character...don't I? And if you dare to be an Abel to your fellow men...well goody-goody...i won't slay you...I'll slay your character instead...won't that do? For who? For ME of course, you fool!
I am Cain, I survive, through it all.
At the very first selection, my genes triumphed over yours.
And through the ages my seed has multiplied, a million-fold.
My tools were many-the monarchy, the church, the aristocracy, the communists,
My aim was one- to destroy you.
After all Abel, I CAIN, was asked to be your keeper.
