Bullies are humans too and have their own problems. Plus, hate doesn’t help us deal with it or make the unwanted behavior stop. And, hate doesn’t feel good. Hate is triple plus bad.
If someone is set on digging themselves into a hole, you really do not need to help them. You can encourage them to NOT dig that hole, but if they are set on it – let it go. Sometimes you win by not fighting.
Even if you are not in health care, you should care about bullying and harassment, because – bullying and harassment lead to bad decision making. It affects everyone and every company and every school.
