You bring up a good point. Uncaring, robotic response to circumstances normally demanding sympathy or sadness is one of the problems I had with stoicism when I first started investigating it. It just seemed inhuman. As I read more, however, I came to feel that what the stoics are talking about isn’t so much unmoved, uncaring non-reaction as it is guarding against letting unavoidable things like the senseless death of a soldier in war time grievously upset you. Especially for prolonged periods of time. In my opinion the proper response to something like what Petya experiences here is heartfelt sympathy and care for those affected combined with a thoughtful reflection on the inevitability of death and a resistance to the impression that death is, in the end, something so horrible. That’s a tough order though, to be sure.
