These are some interesting point of views. In my opinion I am going to cut Jasmine some slack. Till now she seems more grey than a completely negative character.
Having being sheltered from a young age and always rescued by her older sister she is childish and stubborn. Right now she is blinded by her emotions and does not completely realise what impact her actions will have on tejo. She still cares about her sister but right now her priority is Fateh.
At first she was just a girl with misplaced priorities but good intentions. With the new promo she seems like someone with psychotic tendencies. The upcoming track seems to be heading towards 'Jasmine is the biggest Villain' direction.
If they get Jasmine and Amrik married in the future...this could not get more stereotypical. A redemption arc would be lovely instead :)
