Yes, abusing your position of power to use professional assistants as personal maids is bullying. Maybe that was okay in the 90s, but no, that's 100% not appropriate.
Also, I'm sure the psychological harassment isn't to the walls, but rather punching walls is a form of manipulation to intimidate people around you.
Making what up? This comment doesn't make any sense. Being an assistant is a job at a place of employment. It doesn't involve doing highly personal tasks that you would expect a maid, or more likely, yourself, to do.
It's one thing to ask one of your employees to go to the break room and make a cup of coffee for you. It's another to ask them to go to your literal house and do common household chores. That's very obviously not appropriate and it's kind of mind blowing I have to spell this out.
