I don't think anyone who intimidates students of any age should be teaching; learning should come from.engaging, motivating and inspiring your class, not scaring them in to it.
If a student, especially a YL, feels intimidated by a teacher you risk turning that child away from the subject. I had a young student last year whose previous teacher (at her state school) had scared her so.much she was automatically petrified of.me and wouldn't say a word in class. It took 2 months of very patient coaxing and eventually she learned to trust me and open up and I'm proud to say she passed her Movers exam in June with full marks. But it was a long road for her and I had some harsh words for the state school teacher when I saw her. (she had shouted at the girl and called he an idiot for not knowing how to say something it transpired the girl had been absent during the teaching of)
Not every teacher, no matter their dedication, is suitable for every style of teaching. Being dedicated to your students progression is paramount, but if you scare the youngsters, perhaps you are more suited to teaching older teens or adults. There's nothing wrong with that, you just have to find your niche and work with it.
