Frail existance demolished by strife -
Living in pain is having no life.

^I don't like just this two lines, because they have really typical rhyme and rest of this poem is excellent and whole piece has fantastic original rhyming except this two stanzas, this is just my opinion, but I think that life and strife sounds really bad...
existance should be existence

Anyway great poem, it is truly dark and your great talent amaze me...
