It is very unfair to judge any body’s conduct, without an intimate knowledge of their situation. Nobody, who has not been in the interior of a family, can say what difficulties of any individual of that family may be.

Our reading
An editorial interpretation.
A judgment about conduct can look convincing while missing the conditions that produced it. The passage draws a boundary around family life: outsiders may see actions without knowing the difficulties within. It asks readers to recognise that limited access before treating their verdict as fair.
