pia a human still??

okie after today epi i have doubts is pia even human?? does she even have a heart?? how n wat made her so cruel?? bani always gave her wat she wanted n suffered the sorrows herself..so wat in the world made pia like this?? should bani be like this as she was the one who always gave instead of took?? n doesnt pia rember anything? do we all have that much evil in us?? can we stoop so low...bani we all know very well doesnt deserve this but then y??? pia is the most digusting inhuman person ever!! heartless...brainless...she is...n it jus funny now she is never punished n bani who never wanted anything or said bad about anyone always get punished for pia's deed! i hope bani now opens her eyes n turns her inhuman sis a human again n shows her true place in the dirt..or out of this world!
