Imagine if
The Harry potter films (which I have only watched one and only managed one book - but I hear they are pretty popular, AO3 seems to think so) went beyond the books and in the last film Harry and his pals got rid of magic and this ending ended up wiping out all the wizards and the magic folks (sorry dunno if the non humans had magic too). So basically Harry and co committed suicide. There would be an uproar, people would be freaking out. There would be so many warnings at the start of the film, so many bad reviews, parents would be going crazy as the kids of the world were traumatised.
Well that is what happened in GO3. And somehow we are meant to be ok with that.
(Oh I just looked up the ending to HP, it was a close thing wasn't it? BUT. BUT they knew their audience and did not do it)
And btw - Crowley hated the sad ones, remember that.
