Mohan vs Addu

"Mohan was right in slapping addu or not??? " This was the ques we viewers faced in whole of the NBT season2.
But the reason I ended up here writing about this inspite of show being off air now  is the few comments I read on YT while watching an episode where Addu(grown up) calls Mohan on Indore station and blames Mohan for everything that happened with him in past 12years.
Few viewers of the show had a view that Mohan was wrong in slapping Addu after that school princi incident, and by doing so he proved that he was a step father. So all in all they totally agreed with what Addu thought about Mohan.
But is this really true that by just slapping a kid he has sealed the title "sautela" . For me the answer is absolutely NO.. A big NO... Why just that act of Mohan labelled him sautela, don't real parents slap for the wrong doings of their kids. Do you really think if Amar was in place of Mohan he would have handled the situation diffrently. 
Okay I agree that hitting a child won't make him understand anything but than not punishing is also not justified when the kid is misbehaving and doing mistakes repeatedly even on being told not to do. Why was Mohan slapping Addu was made such a big issue. Didn't Megha slap Addu later when she learns everything about him, why wasn't she labelled as 'sauteli maa' than.
Also how can one blame Mohan entirely for Addu getting kidnapped, it was just an unfortunate accident  that could have happened in Amar's or Megha's presence too. Just because Mohan was a step dad he was blamed for everything that happened with Addu.
Also Addu blamed Mohan for not listening to him when he called him or when he needed him the most. But what about Addu, wasn't he also responsible for Mohan ignoring his call? We have read a story in schools "sher aaya" , thats what happened there which created a misunderstanding between Mohan and Addu.
While watching the show I used to think how can creatives show such a dumb track of sautela jaap that has absolutely no relation to reality but reading comments, with people actually agreeing with Addu's thought process really make me ponder is our thinking that shallow. That a step parent is always wrong whether its their mistake or not we will just blame the step parent for anything wrong happening to the kid related. Coz for the first time I ever came across with such statement or thinking. Have seen Step mother n daughter relation in my extended family but it was no diffrent than the bond I share with my mother.
