If a boy has haram relation with girl, he will be told to stop being in relation and some more things but when a girl has been in a relation or if she does drugs or any bad deed, why she is been more criticized than a boy?
And is the punishment of hereafter more for a girl than a boy if she commits a same mistake?

This is just the way society views women but when they go before Allah for judgement there is no difference of male and female in regards to sin.
