Me likey. :) Flows really well, I thought; plus I'm a sucker for Ender's Game stuff. Perhaps you could change 'defending' in the line 'is our defending a mistake' to defense ? just a little thing, you know, whatever floats your boat. :) Definitely really good!

this had a good flow and is better than 90% of the Ender's Game stuff out there. please write a funny poem next time!

Our humanity’s gone

Along with our hearts

Our compassion has left us,

Our souls have gone dark

I was just like... Whoa. That was really touching.
