They were all innocent people.  I stole their innocents away, leaving them to rot.

One deadly sin with deadly results left them laying in a pool of blood.  One room is where the remainder of my days are spent.  One mistake was all it took.  From this hole,  I can hear them, their screams make me smile with delight. 

They have no power.  They try to make me regret my actions.  They yell and they whisper and try to show me the error of my ways amd never leave.  They still failed. 
Let one forget his reason for being, they all laid there like fallen trees, arms up trying to protect themselves. Please, Please, Please they would beg.  I didn't listen.

Stuck in this hole for life, stuck with the voices of the damned, I remember how I got here.  I remember the fatal flaw in my perfect plan.  One person survived.  One mistake that proved to be my down fall.  One regret is all I have, not finishing what I started.
