I mean how can a Jedi code speak about balance, when the Jedi order is all about good-goers and destruction of evil.
True balance is quite hard. Getting in harmony with the two opposite Forces.
Neither Jedi nor Sith actually seeking any balance at all. If anything, the right opposite.
The dark side of the force is a cancer created by the Sith. It wounds the force though power can be drawn from it.
Balance is restored by returning the force to life and health by banishing the sith and darkness.
Which is why when Jedi die, they stay dead. Nope, no magically ghost form for them.
That doesn't mean they are escaping from their fate. They accept they are dead.
