Time and time again in canon, JKR shows Draco as not only a bigoted, cowardly bully, but someone who is vulnerable and conflicted. THIS, SO MUCH THIS. He's actually given much more of these little moments than Dudley, who gets his time to rethink his worldview, while Draco is left to flounder in the ambiguous. I too sometimes wonder if he was originally primed for a redemption arc, until JKR became "concerned" with the fangirls and wanted to make a point? (And considering her point was about girls wanting to 'change' supposed bad boys, I understand completely. It's just that I don't think Draco embodies that role within the text.)

And YES, the Fiendfyre scene with Goyle, and then when he breaks down in the corridor afterwards and cries for Crabbe - these are definitely moments that point to Draco being much more than just a bully, imo.

"No, no." I said. "Someone on the internet is RIGHT." HAHAHAHA I LOVE THAT YOU AGREE WITH ME! <3

We must set up a date for your Draco feels and mine, who knows what might happen! ;)
