How did it shape him? He didn't grieve with his family. He didn't follow-up with his son or wife. It's like "OK, I got through the death of the daughter, so that's all I need to know. I'm done."
It doesn't work that way in real life.
everyone handles death differently. but it did affect his personality from that point, he seemed a little more patient. He might not have been seen grieving with his holographic family, but that doesn't mean he didn't grieve in his own way
At the very least it gave him an insight into emotional pain.
