...scolded each worker and enjoyed making them fear him. (Para. 12)
Enjoy can't be used without an object. When we talk about having fun, having a nice time in general, we can either say enjoy doing something or enjoy oneself.
I don't enjoy traveling very much. 我不太喜欢旅游。
Well, have a good holiday. Enjoy yourself, and don't do anything that you wouldn't do. 好，祝你假日愉快 ! 玩个痛快，不要做任何你不愿做的事。
