I want to confirm the general rule on expressions which refer to generality.
Many reference books say that "you should use "zero article + plural noun" to refer to generality. For example, (1) is better than (2):
(1) Children like animals. (2) The child likes the animal.
The books say that (2) sounds too formal, so (1) should be used.
According to this suggestion, when you want to refer to "family" in general, you should use "families".
(3) You should consider victims' families. (4) You should consider patients' families.
However, I have often seen the expressions "the victim's family" or "the patient's family". When you refer to "family", do you prefer to use the simple noun followed by the definite article?
More specifically, which is better, (3), (4) or (5), (6) when you write an essay or letter?
(5) You should consider the victim's family. (6) You should consider the patient's family.
