I suspect that a lot of (real-world) Callous people act fairly pleasantly a lot of the time, because hanging out, sharing jokes, and even making friends is still more fun for them than being a surly loner. But if bad stuff happens to anyone, they don’t really care. They might help a friend, because that makes life easier and more pleasant overall, but it’s not because they care about the other person much as such.
