This is Voldermort transformation, from Tom, to the Dark Lord. I will leave it up to determine the rest.
Though the words and ideas are mine, the character in question is JK Rowling's.
Save the dead
It's hard to resist the voices in my head,
Tis better to be alive than save the dead,
Her face now swims before my eyes,
Leaving me with the impression of days gone by,
Revenge
it shrieks at me, dying to perform,Revenge her death
, but I am torn,By thoughts of good, confusing my side,
Of evil, that says he lied,
My wand now hovering over his corpse,
Blood now stains invisible on my hand,
Footsteps echo and I disappear,
Leaving behind my innocence I fear,
And the voice that shattered my head,
Tis better to be alive than save the dead.
School is now empty for me,
Dreams of death litter my sleep,
Revenge preformed but power tasted,
Dark arts studied rise to power hastened,
Shadow of my former self,
Plot revenge again for my own death,
A mere whisper of its former glory,
The voice delivers its message into my head,
Tis better to be alive than save the dead.
