Yeah he only needed to abandon his wife while she was on death's door to have the right personality, how "talented".
Yeah, I know that's not exactly what was ment, but it can be taken that way and in a sense it's implied, the MC didn't know the previous version of him son he's judging the present him with all his baggage.
Also... leaving your wife alone when she miscarried because you are working and not even trying to console he after? The MC is a pretty disgusting person.
