I could draw so many inferences .. evil is in thought and act ... How some pregnant women are treated in society and unborn is branded as paap, could simply be related to that djinn. When a girl is raped within family and gets pregnant, it could be easily said that ifrit has done it and kill the child... If escapes and grows up then later kill her as djinn .... But interestingly all the borns are girl cause boy precious .... Also kill if the newborn is girl ...
