Fundamentally, humans are beings bound by a destiny.
A destiny that moves them like a puppet on strings.
"JACK!!! I COMMAND YOU NOT TO APPROACH!!!"
They feel fear, happiness, anger, touched, and despair when their destiny appears.
"JACKER!!! HAVEN'T I ALREADY TOLD YOU NOT TO APPROACH! ARE YOUR EARS DEAF!!!"
However, when that time arrives, no one can refuse it.
"Kaisar Donma, I Jacker Khanwald have come to end your life."
They live with a destiny and die with that destiny.
