He's been cutting himself often
From the butcher knives he finds
People have been making his life hell
To just cut a vein, will leave behind his life
this segment needs work. try playing around with the words and use a thesaurous to find words that would ryme better.
the fifth segment is very good, and clever to use jew and world war II to ryme.
i love this, it is spectacular! the last segment is great, but you have one too many lines and it throws off your 'flow' if you will. very good, 4/5.
i bet you'll win that contest! let me know what happens.

Much better, but another small suggestion.
He knows the torture can still progress
'can', i think would flow better as 'will', but if you want the same meaning, try 'may'. and 'still' is a stand still word in this case. it has no purpose. if you get rid of 'still' the lines would also even out better.
'However all of us do know it'
just a guess, but do you mean 'don't' know it?
'He's been sitting, without moving for 12hours'
you might want to somehow shorten that.
i like this poem a lot. it has extreme truth to it and it is well written considering the ideas and the complexity of the topic. well done.
