Declination.

Terse inert verse,
unnerving diction
of repetitious diabolic
deeds of man.

^^ ok, I am going to have a crack at this one.. Is this like a dictatorship or something similar..? Making choices that affect and though they may not be the best or most fulfilling choices, they will continue unless something is done about this dictator..? Is that right.. That's what I interpret from that beginning..

Malice borne of
selfishness, putrid
thoughts take own
center stage.

^^ this person/ dictator is someone mentally not well - hitler? - but as he is in charge, this selfishness must be adhered to or severe consequences may follow..?

No revelation can
deviate the heinous
crimes that continue
to reincarnate.

^^ its mass cruelty - which does lead to believe it involves Hitler and the Holocaust.. Genocide has occurred again since this mass slaughter.. The Apartheid was a lower level violation of this.

Atrocious taste and
grievous faults shall
continue to multiply
expeditiously.

^^in relation to society's cruelty? Society have committed all sorts of crimes against fellow society members for multiple reasons.

Declination of society
and man seems to
be inevitable, a
foregone conclusion.

^^ a simple yet powerful ending - it helps clarify the poem.

Overall, this is a really great poem. It has a sad but important message. The flow was smooth and you have chosen some good powerful words too.
