People can change if they want to. Some people may have good intentions to provide good information, and tried to popularize teachings, but failed in protocol. If a person can check his ego and change, they can do much better, and be a better resource in the community. But it's hard. It all begins within you.
People are in hell when they have low self-esteem.
They are hurt themselves and are not afraid to die because they think they have no value and no respect. A strict sifu can give them disciplined training and encourage them to walk the correct path. Many others thought he was nuts and some would even kick him in his butt when he bowed to them. Perhaps this Bodhisattva meant to be an extreme ideal for us to follow. We should all strive to rely on the correct way and not people.
