I want to know if you think that Snape is really a bad monkey or if he isn't.
I think that yes, Dumbledore id dead. But I'm also open to possibilites such as: Dumbledore could have directly told Snape to kill him if it was necessary, and that was what they had been arguing about; Snape had gone away from the Dark Lord and then rejoined in the fifth and sixth book because in the fourth book Voldemort says that one of his followers has left him forever; or that Snape has actually been with Voldy this whole time. So what do you think?
