In fact, everyone knew that the quality of righteous people varied greatly.
Although most people were good, there were still many with poor character, as joining a righteous sect did not guarantee one would always be a good person.
It's known that many in the demonic path were those who defected from the righteous path, and without exception, they were evil.
Just like the Taichu Sect today, Taichu himself couldn't guarantee that everyone in the sect was good; while not skilled in murder, he knew several with poor character.
The reason Taichu didn't expose them was to give them another chance, considering they had reached their current level of cultivation not easily. In such cases, Taichu generally gave them one more chance.
If they committed fatal errors again during the observation period, Taichu would assign them very dangerous tasks as punishment.
