Nacks the kind of guy who has his entire life planned out.
Nack's just awsomely badass like that. He doesnt care about life or death, wether it's his own or others in general. He just goes on with his life, doing what he wants, and what he loves, knowing that it can all end at any- *dies*
Technically, he did betray the space pirates, but that was because they wouldn't pay him for the "Ball of Fun"
