This seems common from what I can tell across education, especially in health, there is a lot of cynicism and dark humor. It can be a useful coping mechanism but ultimately, I agree it seems really harmful when not paired with real time to unpack.

I wish you all the best with your education, there is plenty of value in learning to care for people.

A friend of mine is a resident, where I found this type of attitude common, pre-vax so a bit different, but definitely very negative. I really admired her because she found the like-minded group and distanced herself when she felt that negativity was rubbing off on her. As a result, she found a great group of close friends and when conversations or topics stray to the negative she is quick to exit and sticks to her principles. I hope you find those people, assuming they are there, who also see the signs and don't want to fall into the spirals of doom.
