What do you think were Hook's thoughts when Rumpel died?

I think he was kind of in shock. He felt like he should be satisfied and happy but couldn't actually feel that way. I think he hated Rumpel as much as it's posible to hate someone but seeing Belle crying like that and how dramatic everything was he couldn't feel happy for himself. Overall, I'd say he was disappointed, maybe deep inside he was expecting Rumpel's death to make him happy (and stop grieving Milah at last) and that's not what he got. Plus, when Rumpel died he had already moved past the idea of revenge and killing him and his anger had decreased considerably. Also, Hook had proably expected that if the invincible Dark One died it would be by his one hand and not killing himself to save everyone with such a heroic death. (Anyway, I don't think he's really dead but that's a different matter) What do you guys think Hook was thinking?:)
