How about cases where it is right to "quit" the family, such as those of battered spouses or abused children?

As I said: "Doesn't mean there is never a reason to stop or change course"; this is different from "quit" in terms of the article. You don't quit a family just because frustrations mount. Leaving to escape abuse isn't quitting, it's survival. There's a difference, which I was assuming was obvious (nonetheless, I expected someone would call me on not including a volume clarifying the obvious and disclaiming all inane misrepresentations; I decided not to include all that until someone went there).

Quitting stops the issue, but it then would often create a new set of problems (eg. income). The right thing to do is become a better person, become the solution, not the problem.

I was speaking about the perspective of the battered and abused---they are the ones who leave.
