Discord annoys me as a character, he's always given as a good example of a reformed villain, but he is directly responsible for at least 3 of Equestria's semi-regular large scale enfuckenings, for which he gets not so much as a slap on the wrist. He also just causes minor problems on purpose at all times but gets away with it because his paperwork says "reformed" on it so it shall not be addressed again.
They could have given us fun redemption arcs for actually interesting villains (give me Chrysalis or give me death), but instead we get this chucklefuck.
Also he's just a bit annoying, for a supposed embodiment of chaos he is incredibly consistent in his tantrums and betrayals. Basically a child, except that they sent the actual child to hell, and then a rock, of which the latter is arguably worse.
(I remain, as ever, @silent-shadow-mlp, this concludes my rant, which you may ignore if you wish as I am sleep deprived and unwell, so I cannot speak for it's sensibility.)
(this is probably one of my hotter takes, coming somewhere between Chrysalis and Celestia should fuck, and they really shouldn't have turned the child into a rock for a millennium.)
There is an important thing to remember when considering discords shitty ass redemption:
He was a fan favorite. Bronies loved a star trek referemce and they enjoyed when characters were jerks. (I earnestly believe that bronies are a substantial reason as to why the writers decided to make rainbow and pinkie into insensitive jerks)
The fans wanted more of the star trek reference but the showrunners realised they couldnt just do the same villain again several times... and then they just made discord a villain several damn times STILL.
Theres no thematic discussion regarding if an omnicient being of chaos could ever feel empathy, and there is no one demanding that this "reformed being" use his powers for good.
And yes, he is astonishingly predctable with his tantrums, its crazy.
Heres a piece of rune soldier dans awesome undead hunt fic that always resonated with me fr. Miss harshwhinny going for the throat!!
The classic thing about discords fame is that its actually very easy to like him if you turn your brain off. Look at all the whacky hijinx funny thingies he does! Hes sooooo goooofy! All you have to do is not think about empathy or redemption or what defines someone who is worthy and suddenly he seems very likeable!
The writers majorly fucked up with him, if discord was in a friend group, hed be the guy that everyone else has a group chat without.
Shame too i think he makes for an exceptional villain the finalyle shows it pretty well, he groomed a child into being a world ending threat then turned her to stone as a scapegoat for his crimes. Epic villany!
Also yes celestia and chrysalis should fuck nasty fr fr
