Need help to navigate through this workplace negativity

Hello there,
I am here with some hope for the relief from the stress. I will be very thankful for your help and time.

I have a very strange competition going within me. Should I fight for the truth or let it go and let the bad influences win?

I love my work and workplace. Suddenly, there was a shift in our environment.

How did that happen?
CEO met one consultant and he just became a puppet of this newly hired consultant. VP1 questioned few things concerning his area of work and he got fired.

Why it matters to me?
Because I used to report to the VP1 whom they fired after 10 years of great service. VP1 was nice person who cared for the people who work under him.

Why they fired that VP1?
Because he opposed the actions of mighty people. I am disturbed by these. I can’t concentrate at work because now I am afraid to lose my job since this consultant doesn't like me because once I had to stop him for his wrongdoing. In one high-level meeting, the consultant was blaming us despite it wasn’t our fault. We did follow some actions after confirming with Consultant’s Account manager assigned by consultant as point of contact. Consultant didn’t like it and blasted us in front of CEO, VP1, VP2 and few other people. Instead of backing us up or asking a single question, CEO has started singing prayer of the consultant. I felt defamed and stressed.
Now situation at the work is worsened. Consultant, CEO and VP2 don't like anyone who stands up and says anything about anything.
Actually, they had a replacement for the VP1 and that person got fired too (within 2 weeks) because she identified wrongdoing and speaking about them.
When she was leaving after meeting with HR, Former HR, CEO and VP2, she made a comment in front of the whole company about me and one more guy saying " Person2 and Person1(myself) are on our consultant's list and they will get fired."
Since that day I feel insecure and disturbed and defamed in front of the whole company.

Please let me know if I should navigate to a better workplace where I have better work-life balance (if any) or should I fight against these negative energies?

This workplace makes my personal life more unpleasant where I am already trying to work with my especially abled kid. I have whirlpool of emotions now and I really don’t want to sacrifice my daughter’s care.

Do I stand any chance legally to teach a lesson to these powerful people? And do I have any chance to get any compensation if I get fired or even if I don't get fired?

Thanks.
