> You should feel the same about your wife or child as someone else's.

I don't see why it should be so.

It makes perfect sense to sympathize(?) and understand that somebody is grieving and is likely going through pain/emotions that I would have gone through if my wife/child has died. But that is not the same thing as me feeling those emotions.

Isn't this the distinction between empathy and sympathy?

They were pointing out the implication in the source material but not agreeing with it.
