I get both sides, especially Hestia's feelings over seeing her life's work go to waste. But I also think they are both naive and self-centered for still viewing this whole mess as simply a quest for revenge and an apology.
Over the story, it's been clearly shown that Diana's incompetence as a ruler is dangerous to the nation.
She aligns herself with a corrupt organization that's monetizing on public health, bankrupted many people and caused a major loss to the imperial coffers because of her ego, ostracizes the nobility, and nearly caused a diplomatic incident. Again, all because of her ego and self-righteousness.
This is beyond a mere revenge plot. This is an actual public issue. If Kael is that worried about the Imperial family authority, he should be the first to push for dethronement.
