BoJack Horseman Theory

I feel like Bojack and Mr Peanutbutter are polar opposites, highlighting the fact that Horsman wouldn't be happy even if he was completely different person.

Examples:

-Obvious one, Mr Peanutbutter is always happy, curious and energetic while BoJack is tired.

-When Mr Peanutbutter has an argument with Diane he's blind to the issue however offers solutions, contrary to BoJack who only acknowledges the issue but doesn't offer a way out.

-When women around Peanutbutter acknowledge and silently accept that he goes after immature women and dumps them when they mature but complain about BoJack dating woman that was in a coma or imminently get angry with him for taking advantage of Penny as if Peanutbutter wasn't taking advantage of Pickles. Also how Peanutbutter hurt his girlfriend psychologically by cheating on her and BoJack on his gf physically by choking her.

-Whatever Mr Peanutubtter does his ideas turn out great, but when BoJack has idea to help his co-worker with her dream about singing it fails, he tries to be responsible for Hollyhock he lets her down.

-Mr Peanutbutter was supporting Todd's ideas while BoJack tried to sabotage Todd's opera.

What if BoJack Horseman hates Mr Peanutbutter because he's polar opposite making him realize that even if he'd changed he'd still not be happy? Because in the end Mr Peanutbutter is also a bad person but because he has that positive vibe everyone around him overlooks it while BoJack knows he's been born with poison and doesn't tries to fight it.
