Anakin doesn't have a great grasp on the finer points of morality, or on what being a Sith - or a Dark Side User - is. He's too young and not really experienced enough with the subject to pull out the differences.

Anakin shrugged - it most likely wouldn't bother him, as he was still used to hard physical work, and while the bags got bulky, they weren't heavy. He'd be fine, and wouldn't care if he did need to carry things. "I don't mind." They couldn't vanish if he was physically touching them.
