It's better if Griffith loses everything he had worked for his whole life - his powers, his influence, his queen, his peoples, his family, and ends up with nothing. If, in such a state, as a powerless wretch much alike to how he was as an orphan looking up at the nobleman's castle and dreaming, he sees that Guts, who as a normal human who did nothing but struggle against the shit hand dealt to him by fate, ended up with a happy family, a beloved hero of the people, a group of friends who loved him, and above all of that, no longer showed any emotions towards Griffith but pity, it would break him more surely than any form of death or torture could. It also fits more with the themes of Berserk being about moving forward, leaving trauma behind, not dwelling on the past nor waiting for some nonexistent utopia to be handed to you.
