Feelings aren't good or bad. They're just weak or strong. Love, for example, is weak: someone loves you, you love them back, you're happy for a while, and then it fades away. But if one of those lovers betrays the other, then you have a real emotion - then you have something powerful, something that leaves a mark you'll never be rid of. Betrayal is the most delicious of all, but it takes a while to set it up, and fear can be just as intense if you know what you're doing.
