It's not a good idea to make human empathy your dump stat.
Look into a mirror, and imagine that the person in the mirror is a different person. Try to discern how that other person feels about looking at and talking to you.
Now imagine that you are the reflection, and that you actually do not exist when the real person is not looking into the mirror. What could you do for your person to keep them looking into your mirror longer, and therefore allow you to exist longer?
Once you have mastered that perspective shift, remove the mirror, and instead stand in front of another person. Imagine that you are their reflection, and they are yours. What would it take for the person and person-reflection that you both are together to be happier in that moment?
There are no NPCs in real life. Everyone wants to believe that their existence has value, even when all they ever do is useless, dull, pedestrian things all day and all night. Maybe they are that way from lack of intelligence or ability. Maybe they once had hopes and dreams of usefulness that were ground down and rounded off by the endless tides of banality and mediocrity, until everything they once wanted to be, or to do, is now beyond their reach. Maybe they discovered that intellectualism was a false promise, and that those who pursued it became lost in self-delusion, believing themselves to be better and more important than others, when in reality they were all just walking slabs of meat that hadn't died yet, just like everyone else.
When someone gazes into the void, they feel that fear--the fear that nothing really matters, that everyone you have ever known or loved or heard about will die, and everything everyone has ever done will be forgotten and lost to entropy. The one thing that salves it for the moment just may be that knowledge that someone out there knows your story, today. If you can submerge your ego, for just a moment, to stand and listen to someone's boring-ass story about some trivial part of their stupid life, without showing on your face or with body language that it is excruciatingly dull, then that person will no longer be empty. You will have put a small reflection of them inside of you, and that might make them happy for a bit. You won't advance the boundaries of human knowledge, but you will make humanity a tiny bit more connected and eusocial.
Is that important? No. Not at all. Everyone you have ever known or loved or heard about will die, and everything everyone has ever done will be forgotten and lost to entropy. Billions of people have lived, died, rotted, and disintegrated, with little more left of them now than a damaged strand of DNA in a fragment of a tooth. And so will you. Any illusion you may have that you, or the things you do, are greater or more important than other people is just preventing you from connecting with those you see as lesser. All that crap you cannot stand in other people--their irrational beliefs and practices--may be their attempt to avoid even glancing at the screaming black maw of nihilism, so it doesn't eat away all their sanity and motivation. They might only be doing it because no one cares to know their story, today. And if you wish to be seen as important, isn't that just your desire to put a tiny reflection of yourself in as many other people as possible?
I put up with people talking about kids and gods and sportsball and food, not because it is important to me, but because it is apparently important to them. I can stand between them and the void, because I'm not scared of it any more. I can help people pretend that their life has meaning, and I don't need to pretend that mine has more meaning than theirs--because zero equals zero. If you only have to peel back one layer to find the empty, is that better than peeling back two, or five, or ten? Is the value of a person in the number of hollow shells they have around their nothing at all? I personally don't need to be considered important or remembered any more. And that makes me boring, because I generally don't talk about myself, or my niche interests, unless someone asks. Nobody ever asks. So instead, I put on a distracting performance, with the existential black hole of the inevitability of utter annihilation by time and entropy as my backdrop.
Get over yourself. You are as individually important as a raindrop in a hurricane. Take the opportunity to dance in the wind before falling back into the ocean.
When life itself has no inherent meaning, what you choose to do anyway becomes performance art.
