It's human nature. That is how people act when they know they're wrong. Imagine if your wife accused you of cheating. Your first reaction would be to ask why she thinks that, you'd take a defensive stance, and then you'd prove your innocence. You'd want to see the evidence, so that you could discredit it with the truth. But if someone was in fact cheating on their spouse, their instant reaction to being accused would be to attack the accuser. *"How dare you accuse me."* They know the only way they can win is if they go on the attack and prevent evidence from being presented. They wouldn't take a defensive stance, because they know they won't be able to defend themselves. So they go on the attack. They try to make you too scared to present evidence. They try to preemptively discredit any evidence before it's presented, or prevent any evidence from being presented in the first place. Because they know they're guilty. The doctor could have tried to explain that your lack of trust was unjustified, but she didn't do that because you're right, and she knows it and can't defend herself at all. And the fact that she lashed out at your family was to scare them, shame them, into siding with her. *"If you side with him, you'll be attacked, yelled at, ostracised by society. If you don't side with me, you'll be shunned by society."* It's human nature for people to act that way when they're put in a situation where they know they're wrong.
