Sleep with villan to prove a point

Before people start bombarding on me as to why I am writing this please let me assure you its only me failing to understand why no matter how upset you are why would you put yourself in a situation just to prove a point or for that matter to take revenge........ why would Kripa's character want to do that, yes we all know from the promos that were aired that Kripa will purposefully in front of Angad flaunt the fact that she slept with Prithvi bcoz Angad did not respect their night together but how can she live with herself especially if she finds out later on that Prithvi was the culprit and yes lets all brace ourselves this will happen at Manik's b'day for sure but I am sorry I cannot seem to digest the fact that Kripa is ready to give herself up just to hurt Angad.....correct me if i am wrong isn't that the same exact thing that had happened in KTH where before Piyush had died Kashish had given herself to him and Piyush had flaunted it in front o Sujal...........sorry but that is plain sick.........if you get intimate with some one bcoz you love them is different from getting "laid" as one would say to get revenge or prove a point in the end you hurt yourself.... as always a child and Angad accepting Kripa later on no matter what is just a repition so where does MISHTI stand in all of this....
