Is it normal to "like" or at least not care seeing people suffer?

When I first watched The Perfect Neighbor—the one where the Karen kills the neighbor—they showed the kids’ reaction to their dad telling them their mom died. It was on bodycam, and I didn’t feel sad at all. I kind of liked seeing them sad and cry. When the kid said, ‘No, but my heart is broken,’ I rolled my eyes and cringed. Sometimes I go back to watch their reactions for fun. Is this normal? (No, I’m not trolling.)

Edit: And sometimes I just dont care when I see kids or people in pain either way.
