How to kill off a character
Remember when Bobby died and he got a whole episode dedicated to his death and the boys were really upset about it and we were upset but in a way it was okay because he was dying for his boys and it furthered the plot and stuff? Then later he ends up coming back as a ghost so we got him back for a while before having to say goodbye to him again seemingly for good, except we have seen him at least once per season in some way.
That is how you kill off a beloved character.
Bobby had been in the show for multiple years at that point and was a universally loved character by both the other characters in the show and the fans. Doing anything less for him would have been unacceptable. Sure, I wasn’t happy to see him go, I cried, but it was well written and executed in a way that felt right and the fact that he has never been forgotten just made it better.
Now let’s skip ahead to present day. To the death of a character who is just as important as Bobby was and who has been around even longer. Surely he would get similar treatment, right? Nope. Instead of a whole episode he gets one scene. Instead of being mourned over and cared about by the characters no one even cares enough to have any feelings about his death. Instead of progressing the story in a meaningful way his death doesn’t really mean anything. Instead of being remembered and coming back in the future we get nothing. He was here one scene being insulted and then the next scene he’s dead and gone forever.
If the writers had the decency to kill off Crowley in the same respectful manner that they did Bobby then it wouldn’t be so bad. Of course we would all still be upset and complaining, but it wouldn’t hurt so bad. Instead we had to watch a beloved character get mistreated over and over only to have him get thrown away never to return. In a perfect world, Crowley would never have died, but if they really, truly had to kill him off they shouldn’t have done it in such a painfully lazy way.
