While I cannot begin to describe my hatred toward a certain concept, a deviant art user successfully summed up my feelings. (Apologies in advance if you wish for me to withhold your comment from the public.)
"It's funny, because I enjoy such characters as
Q, the Joker, and various other avatars of chaos. I would think that Discord
would be among them, since he doesn't even murder, or threaten others with
murder. But in a way, what he did was far worse. Everyone dies at some point or
another; it's a fact of life we all accept eventually. Most villains just speed
up the process. No, Discord did something that no one is ever prepared to
experience, or ever should.
He thrust six close friends into the deepest pits of insanity, and replaced all
of their love for one another with disgust and indifference in a matter of
minutes.
It might sound silly at first, but really think about it. Can you imagine just
how much psychological torment is involved in that situation? I'm sure the five
who were directly corrupted in the maze still held on to some level of
self-awareness, and realized that they had changed completely. Somehow, a
behavior that had not existed before had been hardwired into their minds, and
they had no power to resist it. Imagine the horror that dawned upon Applejack
when she discovered that she had lost the nerve to tell the truth or own up to
her mistakes. The despair that followed when Pinkie Pie lost her ability to
feel happiness. The choking, crushing obsession that consumed Rarity's thoughts
and made it impossible for her to take comfort in the company of her friends.
The terror and self-loathing that ensued when Fluttershy became compelled to
act on every niggling desire offered by the figurative devil on her shoulder we
all have. And lest we forget, the distress and panic Rainbow Dash felt when her
loyalties were torn in two and she was forced to make an impossible decision.
And as if that wasn't bad enough, the very foundations of their minds and souls
were literally shown to crumble over time. They got worse. Mercifully for them,
they probably lost their self-awareness at some point, and didn't have to deal
with the pain and regret of their own actions.
Twilight was not so lucky. Because Discord had done the worst thing of all to
Twilight. He let her remain sane and watch as her former friends turned into
complete and utter a**holes. For a pony like Twilight that requires order and
routine, and has a mental breakdown when things start to go horribly wrong,
this is the worst form of torture that anyone could ever inflict on her. And we
see the effects. She is utterly broken. When Discord laughs at her as she makes
the walk back to her library, she doesn't get angry or (more) upset. She just takes
it.
It's no exaggeration to say that what they all underwent was a very brutal form
of mind rape."

I couldn't have said it better myself and I won't try to. You may say TL;DR, but then what are you doing here? This isn't the place for quick text messages. That's Facebook's job.
With that, I bid potential readers ado.
