I LOVE THIS MANHUA. It keeps catching me off guard. It plays on generic clichés so well. Almost every character is fun to see. Masterpiece. There is also hidden plot that is slowly tying together, it never feels inconsistent.
In my opinion it is explained she removes inhibition on their immoral actions. Meaning the things they do are still by their own will, just without the conscience that holds them back. That does not mean that she is controlling them to do those actions but that when they think about it, key word...
