Let it be known, 

I take full responsibility 

for everything I've unleashed.

 I do not regret my actions,

 but I understand the weight of them.

 But I fear I'm... 

losing control.

 The Cabal are rapid dogs,

 and I can no longer hold their leash.

 I'm ready to do what must...

 I'm ready to finish this.  

Who am I?
