Rapunzel, I see what you mean. That therapist sounds like a poor one...
Ok, so the smile may be nervousness, and someone else commented about nervous laughter when someone falls. I think I do that some too, but I know beside that, when I hear about something bad in the news- car wreck, building collapse, whatever, to people I don't know, will never meet etc, I either don't care or I'm glad.
Seem to be in the <1% group there, everyone else recoils in horror.

Similarly, I can eat dinner say, while browsing the web looking at totally uncensored gruesome accident photos, explosion injuries on medical sites, autopsy photos or surgery, doesn't bother me at all, again, in the <1% group there, everyone else recoils in horror.
I don't know what to make of that.
