That fact that Regina opened up to Emma, about what she is going through, says a lot about her character growth. It is not fair that Robin died, and Emma knows that. Had she not ventured into the Underworld, Hades would never have gotten his powers back.

Though to be fair.... had Emma let Hook go in Camelot, Robin would still have died. Regina owed a debt to the Dark One's magic, and it unfortunately needed to be paid.
