There are many good reasons people may consider abortion.
A girl is raped.
Young teenagers. 13 year olds can not raise a child.
Health reasons, - and again, the thirteen year old thing, there will be complications at birth.
And also, if the baby won't come out "right". It may be somewhat shallow, but if anyone here knows a family who has a mentally challenged child? Well, you have a mentally challenged child for the rest of your life unless they die most likely. It can really kill a family, it's hard on them, their life, the rest of their life becomes based around this kid.

Abortion can help many people. For a lot of people a baby isn't the right thing at a certain time. It's not fair for a child to have to go through that either.
