Is it okay to "make" someone that you "think" is incapable to carry or take care

No! I think that is horrible...My friend got pregnant at 16, and her mom made her get an abortion, and it has changed her a great deal. I think she should carry the baby, have the baby, and if she isnt willing to care for it put it up for adoption, I am pro life, as I feel people only think about the woman's rights and not the baby's. I dont think it is right, but that is my opinion.

You should never ever force a woman to make such a big decision as abortion. It can really traumatize her. What you need to do is try to make her see what is really best for her. At 13 years old, she could die or become incapable of having more children if she carries the baby to term and childbirth. Also, she is just a child. There is no way she can support the child. And she may have to drop out of school in order to have the baby. Make sure she is aware of real life, not just the fluffy fantasy of "lovely dovey babies" that little girls tend to believe. Tell her how much hard work she'll have to put into the baby and how her social life will be over. If she still wants it, after knowing all the fact, then that is her decision.
