Should we report on my Supervisor to top heads?

Question

I along with other co-workers joined together to get rid of a Supervisor who was breaking all kinds of company rules, and policies, and showing favoritism to his wife and a co-worker. He was also falsfying payroll. I and a couple of co-workers who been there longer train this man, and he wanted to get rid of us, because we stood in his way. All of the workers joined together, and we succeded to get rid of him and the two.
A worker who had just started with us was offer the job of Supv., because according to the company they wanted a fresh face to try to run things with no bias. Of course I, along with others were hurt. She made me her Asst.Supv., we was excited about the changes we wanted to make. She couldn't catch on to a lot of things, so I did a lot behind the scenes. Afterwhile she changed towards me, and felt I was a threat.
She then hire a lot of her friends, and doing like the last Supv. She became friends with her boss, so we feel blocked. There's only five of us left.
