Personally i feel that he is holding them with a whip.
How to gain trust and loyalty with a whip? Fear would dominate their emotion. Once they overcome the fear and dare to stand for themselves, anything can happen.
Do we respect our teacher when our teacher is waiting for the right time to whip us? We will only fear the teacher. If there is any chance, naughty ones would perform tricks on the teacher.
What about teacher who gained your trust and you can trust the teacher to be there for you when something happen? Naturally and spontaneously you would be loyal and defense the teacher when someone badmouthed your trusted teacher.
I do not like to live in fear and be threatened everyday.
I will get older faster..... That is why next doors looks older than their real age.
