Dalip is one character disguised as good man.
Dalip is ultimately the reason Heewab went through so much emotional and physical abuse from many sides. I know Gulab was evil woman and nothing excuses what she did to Heer, but I also cannot completely ignore what Gulab was like at beginning. Apart from being classist, she was not initially someone who constantly forced her decisions on family. In fact, she was emotionally available to her sons from their childhood but yeah didn't raise them well.
*Let's just put Heer’s circumstances aside for a moment and look situation from Brars perspective*
When Dalip forcefully married Nawab to Heer, Nawab made it very clear that he did not want marriage. He did not want to suddenly take responsibility for being husband of a woman who had been forced upon him by his father. When Dalip refused to listen to him, Nawab left house. At that point itself, Dalip should have understood that he had created a serious conflict within his own family and also he and Heer's family are the ones who did injustice to Heer, not Nawab's run away and his fake dating lie or Heer acting as Nawab gf has nothing to do with their extremely regressive pathetic mindset and forced atrocity did by both families.
Whether Heer was a good person or a bad person, whether she was helpless or not, should not even be issue from Brars perspective. Their fundamental objection was that they did not want this situation imposed upon their family by Dalip. He refused to listen to them and kept Heer in that house condemning his family as if it's to take revenge on his son and wife. None of this means Heer deserved what happened to her in that home.
Dalip could have prevented everything between Brars and Heer by keeping them in separate spaces as he saw Heer also strongly opposed marriage just like his son instead of just helping her, he kind of showered love on Heer, making her accept to live in their home and unconsciously accept that marriage. He could have acted as a mediator between Heer and his family instead of simply expecting everyone to accept his decision. According to Brars, Heer was forced on them in their house which is true. Later Brars abuse is forced on Heer which is true. Gulab didn't like Heer but hatred was completely fueled by Dalip's incompetency in acting as man. She slowly became a criminal which probably no one expected her to become.
Dalip was person who created entire situation and then failed to protect Heewab from consequences of his own decision and this exactly repeated in Daler track, he kept on showing himself helpless to Nawab not letting his son to act for his wife neither he acted for Heer till the final day. He wanted to help and protect Heer from starting, but he never took responsibility for what helping Heer actually meant and neither he let Nawab doing it. Imo Dalip who has both age and power is more problematic and toxic than Nawab been.
