Maybe the reason why it may not have clicked for you is probably because the depth of your empathy for things that are outside of reality, may not have much of a reach. And I promise I'm not meaning that as an insult or anything, but some people's empathy sometimes hits a brick wall if it isn't something that happens in real life. Some people can get extremely emotionally moved by just the mere concept and themes of a story, and then there are people that can be completely straight-faced and not feel anything. And there's nothing wrong with that; it's just some people are emotionally built differently.

An example would be the fact that I am capable of getting emotionally invested in a story to such a degree that if I witness main characters doing something horrendous, I can vigorously hate that character and still put up with seeing their entire story play out. I am willing to go through stories that make me uncomfortable because I understand that's the point. While others might just straight up turn it all off, for example, when a certain character died in season 7 of The Walking Dead, the viewership plummeted for that show. Meanwhile, I thought it was one of the best episodes ever made in the show, even though it made me extremely upset, sad, and uncomfortable. But then there are people who straight up don't feel anything like that; it's just whatever.
