The thing about Draco Malfoy is there is such incredible potential there…for change, for a new character arc, for inner growth, and maybe even for some redemption
And a lot of people (including JKR I suppose) don’t agree but I don’t think you can ignore the possibility or gloss over the sheer potential there that does exist whether the opportunity it presents is ultimately taken or not
At Hogwarts Draco was a bad piece of work, a racist, bigoted, pureblood supremacist pig and a bully
But then shit got very real. And Draco was scared. And realized with dawning horror that he was wrong. That his family had been wrong. His entire belief system which has led him to this point was wrong. His infallible father and the Malfoy values were wrong.
As he watched his teacher tortured, murdered, and eaten by a snake. As he was given his mission. As he desperately cried in the bathroom unable to fulfill it. As Dumbledore fell. As Greyback entered Hogwarts. As one classmate was held captive in his dungeon and his aunt tortured another in his parlor. As his childhood friend was corrupted by the cause and died. As fiendfyre almost killed him as well but for the will of Harry Potter and a broomstick.
After this and after Harry’s testimony Draco is left with a very clear path available should he choose to take it. Rebuilding in a wizarding world torn by war where he absolutely cannot avoid that he did wrong. Being under duress, being in too deep, not being able to kill, he still hurt people. And knows it.
There is potential there for Draco Malfoy to become more than he was, better than what his father and his name represent. For him to slowly do what he can to get by and reenter society. To privately grieve and feel perhaps unworthy of forgiveness but to hold his head up and try to make amends. Maybe that’s some donations to charities or volunteering. Maybe it’s assisting with the rebuilding of Hogwarts. Maybe it’s studying to become a Healer or an Auror to help people. Maybe it starts with spending time in the Muggle world or exchanging words with Harry or the Golden Trio.
Any person in this situation following an experience like this stands poised with the choice to make different choices going forward. Draco’s life was profoundly affected and I find it hard to believe he would just slink away with no attempt to make a positive difference. In addition to undoing any good he had done during the war, some through inaction and some through choice, this would further ostracize him in society and Draco’s core beliefs center around proving himself/his worth and his determination to help and protect his family and name.
If Snape whom I also love is redeemed in the end despite the lifetime of Dark Arts, cruelty to children, and bad life choices, in this vein Draco (not even an adult during this time) can’t be dismissed. I don’t think he’d continue a life of the status quo and remain an idle rich Lucius imitator unaffected by everything that transpired and not tap into the good that is inside him.
That’s why I’m pro Draco Malfoy and the epilogue, Pottermore, and interviews will never change me. I don’t love him because he’s a “poor victim” or “dark tortured soul” but because I appreciate the events that have shaped him and the changes and morality that could arise from this drastic shift in worldview that would result in a better man.
