The solution nobody wants to talk about

The point of the movie is that suppressing sadness is a bad thing
- It's supression if it's dead?
  
  No, but the act of killing it is.

The kid would become a psychopath that never gets sad at anything and lacks empathy
- I'd watch it
  
  turn on the news.
  
  It would be a pretty fantastic breakdown tbh.

They literally have a 'cease to exist' pit.
- Yeah, but Joy got out of it in like 5 minutes. If I know sadness, it'll float right out while eating my last cheez-it.
  
  Break her kneecaps.
- And yet I will never forget bing bong.

Killing sadness just leaves us utterly empty.
- Wait, that make sense, depression is the lack of feeling, everyone dead, at least in my experience
- One of these days I shall visit the grave of my misery

You can never know happiness, without knowing sadness.
- That just sounds like philosopher dribble peddled to make sad people feel better.
  You can very well know happiness without sadness. It's called ignorance and from what I've heard it's bliss.
  
  Most the ignorant people I know are the most angry, miserable people I've ever met, so idk maybe that's bullshit too
  
  It's not about knowing. It's about appreciating.
  
  It is possible to know one without the other, however the first experience becomes the baseline upon which other experiences are compared and measured against forming a spectrum.
  Take a baby for instance, early in life they are exposed to milk, the feeling of being close to their parents during feeding and the feeling of a full stomach (happiness). However, this becomes the reference point to compare feelings of being alone and hungry (sadness).
  If a child experiences nothing but absent parents and malnutrition, the child will not know it is sad because there is no comparative reference point. Its just normal.
  Another example, a long time ago when life expectancy was much lower and daily life was very hard, the circumstances needed to feel happiness were much lower. A woman living a hard life in an isolated wilderness suddenly receives a fine dress from a distant city and, compared to her daily harsh reality, it brings her extreme happiness.
  Compare that to modern times where daily life is much easier and we have access to almost anything we want. Not surprisingly, people find it harder to find happiness. Why? Because they don't have the comparative negative baseline.
  
  What do we call this, an Appeal to Balance fallacy?
- Literally the beginning of the movie shows that Joy was there alone before Sadness showed up.
- I'm sure they all met her, they work together.

Someone who hasn't seen the manic phase of bipolar.

Somebody didn't get the point of the movie

I mean...
Maybe anger would have, but he wasn't consistently specifically angry at sadness.
\ And maybe sadness would have killed herself, but she didn't.
It'd be out of character for any of the others to do it.
- Anger murder-suicide of sadness
  I think that's called xanax
  
  That'd just put Sadness in jail to be released at a later date
