Remember, this is the series where a girl accidentally built a time machine out of a wristwatch and a piece of flora. Compared to that, a compelling charm trait is downright mundane.
The phrasing is ambiguous, but that's not necessarily a translation error; it could be that the source was ambiguous. From context, I think it's a contrast between personal values and societal norms. Like, from her perspective, if she enjoys hurting people and no one stops her, is there any...
I don't think this is a case of zero empathy. I think it's a case of extreme empathy run amok. She's acutely aware of the emotions of her victims, and that's what's driving her cruelty.
If we live in a world where there are no kind-hearted people and where no one holds grudges against people who treat them cruelly, then sure, I guess? But in that case, I'm counted among the people who don't understand how the world works.

It's not that Furukawa is trying to earn Tojo's forgiveness; Furukawa doesn't understand that Tojo is carrying resentment at all. To Furukawa, cruelty is fun, and having fun is the privilege of the popular...

That's a good point, although a variety of possible factors could be used to explain that away: a rift of social tensions that built up over time, perceived impossibility of supporting the dead weight long-term, deaths of those adventurers who would have refused to leave the rest behind, etc. I...
