To all you Mal haters/Uma fantics out there that say that Uma did everything for the Isle while Mal just forgot it. Have you ever considered that maybe Mal didn't exactly plan to get into an actual/true relationship with the Crown Prince? Thus making her be thrust into a world that she was uncertain about and unprepared for, with camera's and every single eye in the kingdom suddenly on her?
We have no idea what Mal's intentions were for championing for the Isle after Ben's coronation were. Remember, Mal wasn't even given a chance to speak to Ben about the Isle. Because she was sent to Auradon with an 'evil plan' and was busy worrying about what would happen to her and her gang if they couldn't pull it off! Then when she can stop worrying about that, she has camera's flashing in her face and press yelling at her daily!
Mal was suddenly made to focus more on herself and how she was perceived. A lot more than she intended, in the next six months after the coronation. She never planned for this. As far as she knew at the end of things she'd either be back on the Isle without the wand and well dead/wishing she was dead. When maleficent was done with her. Or her mother would have taken over and Auradon would be the new 'dark kingdom'. She never dreamed that she'd end up the girlfriend of Auradon's Crown Prince. Before she met Ben, she never even knew she could have/wanted love. But here she is, and she's trying her best to adjust and make the best of how her life has been tuned upside down.
So yes, the Isle kinda fell slightly on the back burner of her priorities. Could that be seen as selfish? Yes, but remember again Mal is from the Isle. She was raised to be selfish and look out for herself first. We don't even know how much time she and Ben actually got together for her to bring it up.
Also let me remind you all that it was Uma not Mal that could have gotten the Isle shut down and made things worse for them. If Uma's plan to kidnap Ben had gone wrong in any way, and Ben had died on the Isle/from injuries sustained on the Isle...what do you think would happen? beast would have razed the Isle to the ground and closed it off completely! Ben was literally the only one who cared for the Isle's state. If he died all the VK's would have died as well. Uma may be one of the Isle's fiercest advocates. But she is also the one that was a step away from dooming the Isle.
Don't get me wrong, Uma did a lot for the Isle. She always had the Isle's best interests at heart, and is totally deserving of the love she receives for it. But calling Mal the Devil to Uma's Angel because Mal was made to prioritize herself for a while. All while brushing off the fact that Uma could have had the Isle shut down. If her yes, justifiable anger had gone wrong. Is very unfair, unsympathetic and closed-minded!
