It is definitely but itv has no logic , in ek shows villains are commiting multiple murders & kidnapping but they get away with everything.
But since this is EBSS people will try to find logic hence going by logic i think pooja shouldn't have tried to kill PK because this matter is bound to be investigated. Someone who's running for the mayor is influential and well known , unless janhvi has tainted his image in front of public , which I think hasn't happened (yet) hence it wasn't a great move.
I think she could have cleared her father's name by collecting proof instead.
PS : I am yet to watch the past few episodes so this is just what I felt based on the WU's and Spoilers.
