The joy of killing alien animals

The blade stained red    
with poisonous blood.    
I lick it off without    
sheathing my weapon.    
Here they come again.    
Odd animals that I kill,    
each with just one slash.    
Hordes of the critters    
meet their fate this way.    
I notice I enjoy killing.    
Ok, I feel some kind of    
sympathy for the animals.    
I'm so much more powerful.    
They don't stand a chance.    
Still, with each kill    
I get a surge of power.    
It's almost like I take    
the souls of those I kill.    
If this feels so good,    
how will it feel to kill    
bigger things?
