Why killing Piccolo means God death

Like yin and yang, they are opposites that define each other.
You can’t destroy the dark without unbalancing the light.
You can’t deny your shadow and remain whole.

In the end, they reunite—not to choose sides, but to become one.

True power isn’t in purity.
It’s in balance.

Piccolo and Kamisama were once the same being.

To become God, the Namekian split his soul—light became Kamisama, darkness became Piccolo.

But the split came with a cost:

If one dies, so does the other.
