Is it simply чувствовать ненависть?
In a sentence like Он не чувствовал ненависти к своим врагам, what is the case of ненависти? I can rule out nominative plural and prepositional singular, but that leaves genitive singular, dative singular, and accusative plural. I want to make sure I'm thinking of ненависть in the Russian way here (not just a translation of "hatred").
