There are no innocent Space Pirates. They killed them all.
I can almost see this.
Announcer: And SP#2236 is ahead by a whopping 30 humans with that lucky grenade throw!
Well so does Samus.
No, to Samus its not genocide is not a spectator sport, its merely a fun hobby. her hatred for the space pirates stems from the crass comercialization of her favorite pastime they represent.
She hates them because they killed her family twice, first when they wiped out the colony she lived on and again when they annihilated the chozo on Brinstar, where she had grown up after the first time, the Chozo never fought back, having long ago abandoned the ways of war. She now seeks to eradicate them not just for revenege, though it IS a big part of it, but also because they are trying to take over the galaxy and wipe out everyone else, they need to be stopped n.n
heh, I almost forgot that space pirates are too evil to feel sympathy for
