Consider a scenario: As a parent your child has done something illegal.. (doesnt matter how old the child is... ) as a parent if the child is handed over or reported to police or system, the parent is applauded and appreciated to have taken the right path...even if the parent is badly hurt in all this process... another example is father beating a mother and a child steps in to protect the mother...
Now take it the other way around - it is no easier for a child to report a parent to police or legal system... but we dont live in a lawless society... so all crimes have to be reported..specially the heinious ones like killing an unborn child (no longer a feotus) and beating another person...
From this POV lets see where each of our characters stand:
Pratigya : Her dad didnt deliberately kill angad and even at that time she was supporting the one who was right . Krishna didnt support Pratigya in her fight till his dad gave a go ahead... remember the scene where Krishna scolds Pratigya at the dining table and she goes crying in their bedroom.... he supported her wholeheartedly when he came to know the truth about SS... again when she reported SDS and KN she is again supporting the right thing to do... also she is worried about her future security... hence SDS and KN crime has to be reported.... what will the people do when Pratigya loses her child, or she gets harmed by the REDS or inadvertently Krishna gets harmed... what if one of Pratigya or Krishna loses their life!! that time will the people who are not appreciating what Pratigya has done today be able to bring back time or life??? (agreed this is a teleserial... but in real life one doesnt get so many escapes)
Krishna: In the scenario I mentioned at the top..it will be very difficult for a parent..similarly it will be very difficult for a child..but each adult has to understand that every action will have consequences, good or bad...and accepting that is what make a person adult and mature... only in india we are ok with the idea of crime going unpunished.... (forget the legal system's process for now.. as a society when we protest against it it will improve)... hence even though he is hurting for his mom and brother...... they have committed a crime...
Komal: She is being totally immature... tomm when Adarsh is hurt she will want punishment for the person who has caused the accident...
Kesar: Lost case... doesnt understand that she was punished and her child killed because she was trying to warn Pratigya... so now when she has lost the child and case withdrawn..what will stop REDS from harming Pratigya or her...
Hence Kesar, Komal and Krishna are all at fault in someway...
