Courage is contagious.
It takes only one person/ voice to confront wrongdoers whose actions are uninhibited. If we engage with them physically or verbally, they will know they are not right, and they may be held accountable for their acts. If someone attacks you physically, fight back to the best of your capabilities. Shutting our mouths is our validation to their mistakes. For example, one time I worked in a clinic back home and a doctor was giving unnecessary treatments to earn more money. I told him this was wrong and that he should stop, but he didn’t like it so I changed my job. Be brave. As another example, the #metoo movement started with one voice and it spread all over the country. Now we have an unbeatable army of survivors of sexual assault.
