To clarify, this is just a poem. I'm not actually a psychopath. I'm just capable of channeling one (metaphorically speaking).

The beginning is rather nasty, but if you read the rest, it gets better.
Slash and burn
Burn, burn every bridge
that you come across!
Burn the air that you breathe,
And the blood that boils!
Tear the raw flesh
From the skeleton
Ingesting the fresh meat
Drooling over its succulence.
Swallow the juicy connective tissue,
Choking as it slithers down,
Into acid mixed with bile and pus,
Oozing through a black snake,
Into an endless dark void.
Slash and burn
Burn, burn every bridge
that you come across!
Burn the air that you breathe,
And the blood-filled boils!
Carefully calculated
Rape and murder for lust,
For sport and curiosity,
and greatest of all,
for no particular reason!
All beings are less than insects,
Less than the organelles of a bacterium,
Mere objects, for my own pleasure,
My own sake; mine,
Hahahaha, mine,
preciously mine.
Let them all be gathered into a single heap,
A single pile of mutilated, mangled bodies,
Drowning the cosmos,
In forever-rising rivers of blood and semen;
This world, my world.
All mine and mine alone.
As I take my second bite,
I feel dissatisfied.
I cry, because I am all alone,
Alone in my ultimate loneliness,
My hunger exceeds the pretas.
Beings hate and fear me,
Or pretend I do not exist.
When I am gone,
The wise give me not a single thought,
Like a being who rejects another
In matters of love.
But whenever I arrive,
The wise publicly insult and shame me,
Like cruel parents,
Who tease their children in public,
Sharing their every intimate detail,
That the child would prefer be unspoken.
May all beings not fear this dark mind,
Or feel pity, or self-righteousness,
Or doubt and despair.
May Guan Yin's thousand hands,
Collect the infinite tears of the world,
And turn them into a warm heavenly rain,
Raining down happiness upon the world;
A downpour infused with sunlight,
Projecting rainbows across every sky,
In every realm, in every mind,
Until all the hells are empty,
The hells we create for ourselves.
