You’re upset. I get it. I’m upset too. But there’s being upset by actual canon and upset by the personal fanon you’ve developed in your head. Aziraphale can and NeEDS to be critiqued, but he should get the same depth of analysis people are willing to give Crowley.,
And there’s a bias at times for fans of Crowley to set him upon a pedestal of perfection and excuse his actions.
Both are flawed. Both make errors. Although immortal and millions of years old, both are still learning at their own pace. They’re learning from humanity.
Perhaps you’re a huge DT fan and give the character Crowley the actual actor or other character’s he’s played personality. Perhaps you dislike MS and his Twitter presence and marriage and acting choices and give those dislikes to the character aziraphale.
Perhaps, deep down, you think chubby people should be groveling for their flaws and thin people you find hot require understanding.
It’s a little odd how fandom falls over themselves to forgive Crowley for any thing he says, anything he does- but if aziraphale had done the same thing, he’d get crucified. Even Crowley doesn’t blame aziraphale as much as fans do.
So go on. Write your essay on why everything aziraphale does is wrong, cold, cruel, and abusive to Crowley while Crowley’s choices deserve deep thought and care to their foundations. Crowley will be there waiting for aziraphale, understanding, even if you’ve written aziraphale off as unforgivable.
