It’s not Discord’s fault, yes, I know it’s unbelievable to say this, but the whole story is imbued with extremely strong arrogance where those who do not have the right to call themselves “knights” or “element bearers”, meant to have it absolute right to decide everything and then launched very serious transgressions that are completely unforgivable, as by taking the magic for many centuries from the abyssinians as one of their many crimes.
A mistake can not open a new mistake, and a crime can not justify a crime. Instead of helping their corrupt friends, they chose to annihilate them, and then destroy their realms that have been harmed for a whole thousand years until now! This is worse than what Discord could have done, as he spread disorder, not destruction in his chaos. Here, these arrogant monsters had chosen to prey on others in sheer self-interest in the belief that they are “über alles”.
This is Nazi behavior.
