Sonnet Emmet

Sonnet ["If I were fire, I'd burn the world away"] by Paul Violi
http://www.poetryfoundation.org/poem/249368

This poem follows the Petrarchan  standard for sonnets. The first two quatrains, which constitute the octave, is typically meant to contain the argument of the poem. In Violi's work, however, the argument is intentionally avoided. The entire poem consists of conditional, hypothetical observations that describe the writer's would-be willingness to wreck havoc.
There is no defined volta for this same reason. Despite the formal alignment with Petrarchan poetry, he never offers a conclusion or a reason--he only provides statements of fact. I read this as meaning that, if he were in any of the various positions of power specified by the poem, he would abuse his power. Those who can, do.
The rhyme scheme alternates throughout, as all it does is add musicality and intermittent emphasis, there is no consistent pattern.
The lack of conclusion makes the author's point more clearly, as he cannot give any reason for the actions. He does not claim that abuse of power is legitimate, only that it is a matter of fact. For that reason, the modification regarding the volta strengthens his message.
