Ethical Violations at Work

You always talk about peace. So want to ask you this question that has left me restless, sleepless and devoid of peace.
I am a researcher who joined this lab of a very senior scientist where I found lots of wrong things happening. When I pointed out these to the senior scientist she turned against me and did ever possible thing to isolate me and mentally torture me in the lab. Finally I decided to leave the lab. However my friends advise me to complain against her before I leave. I want to leave in peace but still want things to change in the lab for other people who are there and people who will join in future because what’s happening right now is unethical, immoral and cruel. If I make a complaint against her, isn’t it a violent action on my part? But if I don’t its awfully wrong too making me a party to the non compliance.
