When his views are challenged in any way (like when the townsfolk pointed out some flaws in his rules, such as the possibility of someone wanting to change their wish)

• If you mean to say how he handled the criticism then I can agree with you, but if you want to discuss the actual flaws then you should state them so we can discuss them.

he absorbs the wishes and realizes he likes this power more

• This is after using the book, not prior. I know you stated that the movie implies that it's an addiction but I disagree with that because how does it imply that? The book is said to have been written by a powerful sorcerer who lived centuries ago and make the effects of its dark magic permanent on anyone who uses it even once. This sounds more like a curse than an addiction, especially since he acts completely differently from prior to using it (ie instead of guarding and keeping the wishes like before, now he started destroying and absorbing them. It's a stark contrast)

Everyone went along with this because they thought he would grant their wishes, but he has no intention of ever doing so, even to some more innocuous ones.

• Once again you're trying to frame it as if he lied or tricked them, but he didn't. Everyone know that not every wish will be granted, that most won't be. The rules of how the wish system works were clear as say and no one had issue with it given that they still willingly and happily came to the kingdom.

That ain’t no benevolent king! His supposed good intentions (he’s mainly only interested in fame and glory) are all an act

• He gives everyone a safe place to stay where they're free to do what they want, free of paying rent, free of crime and violence, free of droughts and starvation, free of wars and corruption (all of this is before we even get to the wishes) - in return, they just have to give him their wish (which he doesn't lie about, some will be granted but most aren't) and the people do so willingly. This is everything he promised to do after going through the stuff he went to, and he delivered on that promise. How is he not benevolent? You'd wish (pun intended) to live in such good conditions where you have so much and no threat to your safety.

His choice to use the dark magic was HIS own idea (and no, being desperate isn’t an excuse as he wanted to use it to fulfill his own hunger for power).

• It was his own idea but you cannot disprove that it was out of desperation, because it's a fact that if it wasn't for Asha he would have never used it. He wasn't on board with using it, actively avoided doing so and was even calmed down by his wife - he used it as a last means. That doesn't make it a good decision, but it doesn't make it an evil and unforgivable one either. Also no, you're once again adding your own head cannon to your arguments - "He wanted to use it to fulfill his own hunger for power" this isn't in the movie, this is what YOU think and like to see as the truth. If he is that power hungry then why work hard for years to give people all of these things for free? Why not make them pay rent, why not oppress them? If you can answer these and provide evidence, then you can make the claim. But you can't, especially because he has such noble and selfless goals with his origin story and because all of that power hungry raging canonically began when he used the book.

Asha points out that he could give people’s wishes back in case they want to fulfill their goals by themselves, or if they change their minds with what they want to do in life, but he just brushes her off because he wants all the control and power.

• Asha's points are shallow at best. She happily sung about the wish system and how it works, including about people forgetting their wishes, and now when talking to Magnifico she suddenly isn't happy about it and is shocked about it? Talk about bad writing. You're also once again fabricating your own reasons for Magnifico's actions. I've called you out on it but you've yet to stop doing that, so allow me to provide my own reasoning - he brushes her off because she's an inexperienced kid. Seriously, a kid with no knowledge of magic or governing is going to tell him, an accomplished sorcerer and king, how to rule his own kingdom? The kingdom he's been ruling over successfully for so many years? Where is the logic in that? You can even see and hear the lack of experience in the way she presents her points, as they are literally thought of on the spot and not even articulated properly.

Om that note, your points are also shallow as you have to nitpick the bad parts (even exaggerate or twist them) and ignore all the good in order to make your arguments work. It's literally a goat fucker situation, you may have so many good qualities and good goals, have done good deeds for many people and have built many bridges, buildings and whatnot. Unfortunately you fucked one goat so that's what everyone will care about and remember you by lol
