Casca should be the one to kill Griffith not Guts.
A possible scenario is Griffith hesitating or being genuinely shocked when Guts doesn’t fight back and lets the sword pierce him. (Just like it happens with Casca many chapters ago). Which gives Casca an opening to kill Griffith just like she did to that nobleman when she was first recruited by the hawks. I’d be poetic. All the parallels are right there.
That or Griffith’s gets to live as a monster and his kingdom eventually collapses after his real nature is revealed, making people abandon it. Now everyone leaves just like Guts once did. But now it isn’t out of respect, but out of true disgust. Maybe the kingdom still stands, but with no inhabitants. In the end he is a king of nothing and remained a monster. Maybe the consequences of his actions finally down on him.
I want him to realize he threw away something invaluable when was still within his reach (the band, Guts and Casca) similar to Guts’s realization. I really want Guts and Casca to haunt him the way his actions haunted them. Is only fair.
I really want Griffith to feel the weight of his guilt and shame over what he did to the band, Guts and Casca.
And I want everyone to see him for what he really is, not a savior, but a broken and fragile man who committed unredeemable acts of evil on moments of desperation.
There’s no way midland will stand by his side once they discover he was the reason the world went into decay and his kingdom is a fake paradise build on corpses. Not to mention he killed the Queen, Charlotte has to know the truth, about how Griffith killed her mother
Apologies if you're not the same anon, but these asks are similar enough that I'm gonna group them together.
I do love the idea of Casca being the one to kill Griffith or Griffith living but being haunted, both great possibilities! I can never really buy the idea of Falconia's residents like, turning on him when his "true nature" is revealed though - I don't think there's a whole lot to reveal, and nothing that would have an effect on a city's population. They're already cohabiting with reformed monsters, Griffith having a cool goth look and some dead and traumatized friends behind him isn't gonna change anyone's opinion. Even if it's somehow revealed and universally believed that he flooded the world with monsters on purpose, they're still gonna pick awesome city with indoor plumbing over hungry dragons.
If he survives, I'd prefer him to just lowkey be trapped in a loveless stasis while ruling the world, never truly fulfilled or happy. But I also like subtle angst more than big dramatic gestures tbf lol.
