I can think of various people who have treated me absolutely appallingly, who I find it impossible to have any kind thoughts towards, so I suppose I hate them. But there is one woman in particular, who bullied me mercilessly, and who continues to harass me long after I've moved out of her orbit. This is a woman who expends energy to try to grind me down and make me miserable.
Even though I hate everything about her, I feel sorry for her, because unlike me, she can never get away from herself. And if she died I would be very sad for her, because, short of a miracle, she's going to hell.
