What is the reason why the eight characters are not ruthless?

It's a bit embarrassing to kill and reprint lightly. Timid, bully the weak and fear the hard.

Killing and printing are all heavy and weak, and their ability is poor. Flattery

Killing seals is light, but it is too strong, courageous and unpractical.
