Yes, Raskolnikov. He was basically thought that the old hag was completely useless and even harmful for everyone. And having her money he could have done some good deeds. He also thought that be it, Napoleon, in his place, he'd not waver for a moment if she stood an obstacle to his plans.

But let me put it this way... Raskolnikov wasn't Napoleon. He was a conscientious guy and, if anything, wanted to prevent his sister to marry a man she didn't love because his sister wanted to do it because she could help him.

But when he did kill the old hag, he experienced horrible torments of consciousness and that was his punishment. He couldn't even use the money that he stole as he became nauseous even thinking about it. So when the detective eventually figured it out and sent him to Siberia to do his time in penal servitude, he felt relieved. )))
