Is there any Torah commentary that addresses how Yaakov’s ten sons could have been so cold, heartless and cruel, to cause Yaakov’s intense, 22-year, unconsolable grief over Yosef’s death? What child puts a parent through such hell?

[Bereishis / VaYeshev 37:35](https://www.sefaria.org/Genesis.37.35?lang=bi&with=all&lang2=en): All his sons "***and all his daughters***" tried to console him, but he refused to be comforted. He said, "I will go down to the grave mourning for my son." [Rashi](https://www.sefaria.org/Genesis.37.35?lang=bi&aliyot=0&p2=Rashi_on_Genesis.37.35.1&lang2=bi) says that each of Yaakov’s sons had twin sisters. Yaakov actually had 14 daughters: one daughter was born with each of his sons – except for Binyamin – making 11 and then there was Dinah, and Binyamin’s two twin sisters. They subsequently died by the time Yaakov entered Egypt, as evidenced by the fact that they were not counted in VaYigash as part of the 70 who came to Egypt. Yaakov was therefore a bereaved parent 14 times over for the deaths of his 14 daughters. This makes the brothers' causing their (bereaved) father Yaakov to grieve even worse. What child puts a bereaved parent through such hell - again?
