It depend's on the condition, environment, Health and many more.
If giving a birth may cause death of a girl then i say it is good to abort.
If mistakenly a girl is Pregnant and she has already got 2 child or more and if she don't want more then I say it is good to abort.
If a girl is pregnant because of rape then I say it is good to abort.
If a teenage girl is pregnant because of her immaturity and due to many other reason if family finds it is good to abort then I say it is good to abort.
BUT
IF ONE WANTS TO ABORT A CHILD COZ CHILD IS FEMALE THEN :chair: :chair: :chair: :chair: THEY ARE BAD PERSON.
