As much as we try to be good human beings, its very tough to overlook the FACTS about someone's past, be it their fault or not. This is especially significant when it concerns your own. In fact we have dealt with something like this where the father has a criminal background and for that reason the daughter was being rejected for marriage. At that time we asked "is it her fault"? Why do the parents wrongdoings have to affect the child's future? The answer was "Yes its very important to know what the background is, because, its like they say in SGP itself "if the root is good, the branches will be good too"... to a certain extent I agree but not fully but I really don't think that there is a right or wrong in this situation because everyone is right in their position. As parent KK is right and so is RB but Sanju and Deepak are not wrong either. I guess it just comes down to circumstances and how they pacify each member for the alliance!
