The Carcass Derrick

I left a human all alone 
  Helpless.  Wondering Why? 
  How could a human do all of this? 
  What have I become? 
  Love for revenge-consuming. 

  In my design of death a carcass derrick was born 
  (Assembled with death, fantasizing of the uses to come) 

  Rusty pulleys and hooks 
  For suspension of living carcasses 
  (Fashioned with actual human skin! That's just how we do it on the farm.) 

  Alive or dead - hung upside-down and bled. 
  Into troughs - slides indiscernible slop 
  I hesitate - catching every last drop 
  If alive - can't run as legs are chopped off 
  When deceased - cleanup is with such ease 
  Sterilize - man-made human killing machine 

  All your fears now realized. 
  There, dripping, dangling and hogtied 
  Terrified. 

  Your whole life now marginalized. 
  There, disemboweled as we let you die. 
  Horrified. 

  Since when have you ever been so merciful? 
  I cannot recall a time you cared 
  With your intestines clenched in your hands 
  Now you scream for forgiveness 
  There can be no mercy in the carcass derrick 

  Alive or dead - shan't leave here with your head 
  Into troughs - rivers of blood, juice and snot 

  I rejuvenate - savoring every last drop 
  Never to scream again - your ugly head is now lopped off
