I've seen this before -- in my own family

My father was a malignant narcissist and an authoritarian.

His rages were epic.

I was a regular target as I stood up to him even when I knew it was a futile effort. I wouldn't agree with him when he was wrong, and unfortunately, he often was as well as having poor judgment. And as a result, I was branded as a "trouble-maker" in our family.

Our mother also argued, but sporadically as she too knew it was a futile effort.

My sister became an enabler of our father and began to harass me, partly to protect herself and not as much, to protect me.

My brother just kept out of the way.

Our family was classically dysfunctional.

I can see how the Republican Party has become afraid of making Trump "mad".
