The reason why Han Lao has become like this was also because his father not willing to have over the Han Industries to him after his brother died, but in fact, gave it to his brother's widow.
Of course, he would not be able to understand the reason why his father took such a decision.
The reason was simple, the person who did anything wrong would not know if he was wrong or not if one were to ask him from their perspective.
And something similar was happening with Han Lao.
He was not able to understand that the reason for him not being given control of Han Industries was not because his father felt pity for his elder son's widow and daughter, but because he was not good enough at managing such a giant industry.
But, the one in the wrong would never be able to understand their mistake and this was the same for Han Lao.
