Metroid - Why do they do it

Last submission of April.

When Samus finally reached Phaaze, she realized something. Phaaze is one hell of a planet.
Samus could ask herself: 'How do I get rid of a whole freaking planet!?'
Not to worry, Samus! Dark Samus has it all figured out already!
All you have to do is to fly down there and defeat her new toy. That shouldn't be too hard.

Samus speciality: "Indirectly" destroying planets.

If you don't remember or played the game:
The Space Pirates stole a biological computer and Dark Samus wanted for some reason hook it up to the evil super-planet.
Of course you'll fight it, but when you defeat it, the whole planet blows up for some reason...
