A villain's last line

Stumbled upon a writing prompt about villain's last lines, so decided to give it a try.

(it is more like a poem though.....and it is a bit bio related. Studying biology messed up my brain....also i just need your thoughts. since it was just a writing prompt)

"They labelled me a deadly virus, not knowing i was dead inside
They said i fed on others, not knowing i was just trying to survive
They sent a hero--the antidote they found--to kill me
They cheered for him while cursed for me
But I saw the hypocrisy hidden behind their words
Had their antidote--the hero they forged--failed to destroy me
They would have discarded him as a failed tool
So I chose to die for i saw the life burning inside him
While i was cold with only the smoke of embers inside me
After all, What use was there for a deadly virus to cling to a corpse?

It was finished. The antidote has won and the plague has lost
Yet was the gratefulness of the people, the cheers of the hypocrites worth it?
Was it worth seeing the flicker of fear --that hint of life-- in those eyes?
Was it worth watching that shine of humanity in the labelled monster glow dimmer?
Was it worth being haunted by those lifeless eyes for the rest of his life?
No. the truth was, the hero had lost the battle.
He didn't defeat the evil: the villain has already lost hope
He died --hoping to save the burning fire of life inside the hero
Yet his death released a river that would forever extinguishes that fire"
