we all know ad lib is based off macbeth now, right. if you weren't forced to study it in school, this quote was said by the witches when referring to banquo, saying he wouldn't be happy, (he'd never become king) yet much happier (would never be driven mad because of it)

this really reminds me of shadow milk and silent salt. In the end, ss dies on the battlefield, and to most people, that would seem like him losing, but ss is happy in death because he believes he has fulfilled his purposed and saved everyone from dark enchantress' tyranny with white lily. He does die, but he dies satisfied and at peace.

Shadow milk gets what he wants, and this should make him happier. but the power he has absorbed from his dead friends and the ultimate cookie has made him weak and is driving him insane, both from his growing need for control and the influence of the other beasts on his mind. Every time we see him onscreen, his stability and mental state are visibly deteriorating. silent salt is "not so happy, yet much happier" than shadow milk in this way.
