It was a great pain for Rey to see his wife in the arms of another man where the pain and blind rage made him kill him, only to get revenge, but this did not make his pain calm, but he was without food and sick from his agony .

We can see that the king despite seeing him both killed, felt the nail of betrayal in his present life, making everything around him seem the same, that he didn't even try to eat, he was getting sick due to the pain of he.

But when he saw his sister-in-law do that, having relationships with other people, he saw that his brother would be worse than him, the situation he experienced with the deception, he felt relieved, that if he was wrong, his brother would be Worse, how would his brother's attitude be like that of him killing everyone to cover up his wife's deceit?

It is an attitude that changes when he sees that his brother's wife is worse than his own, that what he saw made everything feel good, that he did not feel anger because his brother was being cheated on, but rather that he felt it was a relief, This is a feeling that is born when we see that others are doing worse than oneself, in the human being.
