Bitter sweet - means that a situation has both good and bad parts. You are partially satisfied and partially dissatisfied with the outcome of a particular situation. Living dead - is a fictional concept where the body of a person or animal is animated and appears to be alive, but is actually dead due to the lack of a heartbeat. Usually we term "living dead" as "zombies." Delicious hatred - means is that even though a person hates another, that person gains pleasure from feeling that hatred as well. This may be because they are sadistic, or perhaps they feel their hatred is justified. I hope my definitions make sense to you. If you have more questions, please ask.
