Satan's Soldier

In the day I sleep, in the night I dine
Feeding from those whom often decline
Their screaming souls, I drink away
Leaving their shells to slowly decay
I'm a slave of the night, a master of death
An expert at stealing a mortal's breath
Be him strong or be him weak
It is but his blood of which I seek
You may say, I'm a monster of such
Friend of the devil, his soul I clutch
But it is my job, to take mortal lives
I feed on humanity, so that evil survives

*Obviously, this poem shows the upside of being a vampire, but I have written another one which shows the opposite called 'A Vampire Curse'*
