Withering art

Cruelty is my subsistence,
The repast I have to have.
For the world
I'm just a disruptive behaviorist.
For me...
I'm just the ruler of the world.
Searching for what
They already have,
I simply crush their minds
In my holy hands!
I'm never satisfied.
The other's pains
Are not enough to kill my famine.
I live from disasters.
I die whenever I want.
I fulfill my needs
Through cruelty.
That's the way
I live for you all.
