While it's very easy to fall into this category (and admittedly I did this at first too). To call Beast/Adam the "true" villain of the franchise is stretching a bit. Is he a dumbass for creating the island? Yes, but realistically he would've never gotten away with it if he was the only one who wanted this
I've seen this take by @dani-luminae and @thetimelordbatgirl that someone simply HAD to take the role of "king who locked everyone up" for the story to happen
His actions in the movies is really not something a "villain" would do, is he a huge idiot? Yes and I hate HATE the stupid "No son, it's yours" line during the stupid family scene but considering what happens during the coronation we're to assume they cleared it up off screen
My interpretation of the character currently is that he's a himbo who easily goes along with what the people around him is saying considering how fast he changes his mind about stuff in the movies all the time depending on what's happening around him
Does this make him a very good king? Probably not
Does this make him a tyrant? Absolutely not
And listen, his character is so vague in the movies it's very easy to twist him either way but considering his backstory it kinda make sense if you think of him as a kid/teen who was severely traumatized after being cursed for ten years, like if they could've added just a small thing to make him more sympathetic towards the whole "no magic" rule is that- they could've had him flinch or back away whenever someone uses magic near him
Now I do have my whole own backstory for him to make his character in both Descendants and the og movie make sense but that's a whole other can of worms- to cut it all short
Descendants Adam is an idiot, not a villain
Honestly? This is a very balanced and compelling take.
Calling Beast/Adam the true villain of Descendants often comes from a place of frustration with the premise (Isle of the Lost = morally questionable), but yeah your breakdown makes a ton of sense. He’s not malicious, just incredibly shortsighted and heavily influenced by those around him. The “himbo king who accidentally created a dystopia” angle is honestly kind of perfect.
You’re also spot on about the context he couldn't have done it alone. The existence of the Isle was a collective societal decision, not just one guy pulling strings. Someone had to play the "symbol" of that decision in the narrative, and it just happened to fall on him. The whole idea that he was traumatized from being cursed as a kid and developed some weird coping mechanisms around magic? Brilliant. That would’ve added so much nuance if it was even hinted at on screen.
And yes, the “No son, it’s yours” moment… cringe. It’s trying so hard to be this Lion King type of scene, but it just comes off tone-deaf given the context of their world. Like, sir, your policies exiled children.
TL;DR: Adam isn't a villain, he’s a soft-headed, post-traumatized people-pleaser in a position of too much power. And that’s way more interesting than just labeling him “evil.”
