From Minghe's perspective, Untainted Land was originally a cruel world. Strength was the only thing that mattered in this world. Therefore, he did not impose any restrictions on his disciples. They could do anything. Minghe would not care as long as they did not betray him or harm their fellow disciples.
As long as his disciples remembered these rules, Minghe did not mind even if some of his disciples become a good man like Hongyun, or a carefree immortal like Zhenyuanzi, or even a peerless devil king like Luohou.
In Untainted Land, there was no law to decide whether one was good or bad, kind or evil. Minghe himself did not know if he was kind or evil. For Hong Meng Immortal Qi, he had slaughtered 68 Sages-to-be. Was he evil or kind? Good or bad? He did not know.
