"No matter what kind of person, there are good and bad sides. It's all about how you treat them," Flying Fish expressed his point.
Ye Hao understood what Flying Fish meant. Flying Fish was implying that it depends on Ye Hao's instructions. If Ye Hao orders them to do evil deeds, and they indeed do so, then they are bad people.
If Ye Hao orders them to do evil deeds, but they refuse to do them, then they are good people.
This was Flying Fish's way of finding out what kind of person Ye Hao is. If Ye Hao forces them to commit evil actions, then there's no reason for Flying Fish to follow him, as Flying Fish has his own lifestyle and principles.
"If I asked you to secretly gather intelligence, to watch over people I want monitored, or to keep tabs on someone, would this make you lose your principles?" Ye Hao asked with a smile.
