I have a serious grievance at work my area manager has asked what i want done about the person can i say i want him sacked?

My manager is off sick and my supervisor is power mad. We work for a security firm for a building and every thing that happens he ignores policy and reports it direct to the building manager. just before christmas he shouted at a cover guard in the middle of reception because she asked if he was ok a couple of time. he then took a bonus intended for everyone and said he will just split it with the day guards. a few days later he lost his temper and punch the all in one Pc in front of me causing it to break in the middle of reception. My area manager came in and had a word so then he was boasting he can do anything he likes and get away with it.

today i raised a formal grievance and was asked what i want to happen to him and i didnt know what to say. I dont want to work with him he has no idea how to be a supervisor or how to behave towards anyone
