In Berserk Abridged finale, Griffith choosing to remain disabled for the rest of his life rather than sacrificing his friends to become an powerful, immortal demon. Sadly, Word of God says that the Downer Ending truly happened. Subverted, as this ending would make this parody unfunny, so no, Happy Ending is really present..
Judeau: So, they really offered you infinite power and eternal life if you sacrificed us all?
Griffith: Yep, that's right.
Guts: And you chose to live the rest of your life as a cripple rather than do it?
Griffith: Well, yeah, I'm mean you all just risked your lives to save me. I'd never do anything to hurt you.
Also, the first time Casca and Guts have sex. It's really a beautiful scene and a nice change from the usual death and destruction in Berserk. Casca even Lampshades it.
Minor and not necessarily positive one. During the Eclipse, Griffith is told the Godhand can read minds and tries to Think Unsexy Thoughts. Conrad assures him the Godhand is used to the occasional dirty thought, and that Griffith wouldn't be judged. Of course, they realize Griffith is too perverted/depraved even for them, but it almost makes you think the Godhand are nice.
