also, we've all kind of established at this point "sun is an asshole" "sun is the villain of eclipsetale" but is there actually something more to sun's constant jackassery and is he supposed to be more of those relatable villains / not actually a villain at all, or is he just an average antagonist? sorry if this was phrased badly ^^;
This is a good question! But also very tricky to answer XD
People have established a lot of things about Sun. A lot of people have made very dark content with him and that is good! My aus are meant to be able to be used by fandom however needed no matter how dark the content is. I believe that dark fic and fluff fic both have their merits and can both give creators catharsis.
I encourage people to interpret him however they wish, but for some that may lead to a one dimensional character who is pure evil. Which is okay and completely valid by the way, characters don't always have to be redeemed or turn good in the end. Pure chaotic villains are fun!
However, this is not my personal canon for Sun.
Canonly, Sun is meant to be a heavily flawed character with issues that reflect how trying to fix everything and make things better by force isn't the way to go. He's morally grey, a dark dirty grey, but grey.
He's awful, sadistic, and mean but that's not all there is to him. He has heavy codependence and control issues. He's manipulated and hurt many people just to protect Moon. He covers up his own insecurities and pain by hyperfixating on his brother. Sun is not a good character, he never will be, but I hope to share more about his past and eclipsetale's future one day.
At the end of the day Sun was/is Dream, he's Dream if Dream were to see Nightmare hurting and decided that he needed to save him from his pain. Sun is hurting, very badly, and his intentions are good but his methods are awful and only make everything worse. Sun's a Mess and he's desperately hiding it.
At the end of the day it's up to the viewer to interpret Sun however they wish <3
