Hi.. Well I guess the CVS are showing the Krishna kidnap to pass a message to the youngsters who now days act without thinking and only think of revenge the track is yet not over friend and im sure they would show Krishna regretting when maybe as spoilers states Shakti will try to get physical with the girl. Then Pratigya might explain to K that he could have ruin the girls life and just as he doubted pratigya after knowing that she was kidnapped by Angad maybe this girl would have to go through this too...
As far as K is concerned its not that he simply acts without thinking its that the way or the family in which he is raised causes him to act so you must have noticed all the thakurs are agrreing with this act except for the Saxenas.
