The killing choice

Today I want to kill a man  
But i need to formulate a plan  
 
Of how to carry out the act  
Its the part of the equation that I lack  
 
I could slit his wrists and let him bleed out slow  
Release all his worries in a crimson flow  
 
Or maybe get it over quick and be done  
Leave all his regrets at the end of a gun  
 
Can rope him up and watch him hang  
Breath seeping from his body along with his pain  
 
The top of a building I can toss him down  
Let him reflect on his failures before hitting the ground  
 
Hold his head underwater make him fight for his life  
Like he never did for his kids and his wife  
 
A bag over his head he'll die gasping for air  
While he reaizes that now its too late to care  
 
So many fine options how can I pick one?  
Have to choose wisely cuz when it's over Im done  
Wont get another chance to try it again  
The start of my murder spree and also the end  
 
Im a monster and I'll get what is coming you see  
Cuz the man that I will be killing is me
