Lol I guess. I think there's a massive chasm between being ignorant of your effect on someone else and actively inflicting pain, but I'm sure I won't convince you that this is a meaningful difference if you don't already believe it. I think you could argue that tons of modern human activities cause negative experiences for other people, I don't think that means the people doing those things are terrible people. Something as simple as watering a lawn could be construed as "not caring about other people" due to failure to conserve public resources, but I don't get a lot of person benefit from cursing every person with a green lawn in the summer.

It's possible that nobody has ever complained to them about the noise. It's possible that they have never been annoyed at loud noises. Anything's possible.
