[Hoping this doesn't belong in the character development part?] In my story the male character persecutes the girl because he hates her mother, but can't get back at her so he takes out his feelings on this girl. I don't want to have any sexual harassment/assault stuff involved, yet make him menacing/scary. Any ideas on how to do this? He has a lot of power over the girl as he is a teacher in a school where she is being trained as a religious warrior, while she is young she has to attend his class regularly and he has the authority to physically punish, beat etc his students if they are 'disrespectful/not attending to their studies/disruptive' etc gives him plenty of lee-way. Any input appreciated.
