According to some resources I have you use the Dative case after a lot of verbs that mean an action pointed towards a person, like the "to gift" verb. For example:
Виктор мешает брату.
"брат" is in Dative case.
But at the same time I know that you use Accusative case for direct objects, i.e. the object of the action (and, subsequently, Dative for the indirect object). So in the example given above "брат" is clearly the direct object, so why isn't it in Accusative case? Is it just one of many "exceptions" that need to be remembered that go with the Dative, instead of the Accusative?
EDIT: Removed the "to hate" and "to love" verbs.
