No pity for the weak.

[Wildcard]

I wasn't overly fond of the way 'grave digger' was inserted . . . the line was a little long and the rhyme stuck out 'like a sore thumb' if you'll allow the simile.

Other times the rhymes are a little too predictable (for such a serious piece) like S2 L2 & L4, but this could just be personal taste.

I am a fan of both rhyming and non-rhyming poetry, to answer the other question.

Please take my criticisms with a grain of salt.
