Personally, i think abortion is just wrong. It means killing a living human. Even a foetus has life and a heart that is beating. By aborting it, the woman is literally killing something that lived inside her.
The decision for an abortion is usually not valid. For example, a couple had pre-marital sex and feel that the baby is a liabilty, so they choose to abort it without considering that they just created Life. Many other couples want to have their own children but are unable to do so. If a couple had an unplanned child, the mother of the child should at least carry him to the full term. After that, it will be up to her to keep the baby or give it up for adoption. This way, the baby would have a happy home and continue to live.
After all, the baby should not be punished for his parents' mistakes. If the parents choose abortion, they are killing an innocent life. Parents, be it married or unmarried, should be responsible for their own actions and know of the consequences before they do anything.
However, there are times when the reasons for abortion is justified, like the mother who had a high risk of losing her life if she continues her pregnancy of if she had a miscarriage. In the former case, if she goes for an abortion, at least she would not lose her life. Even so, there are many downsides to abortion. Abortion may be harmful to the mother if the instruments used are not well sterilised. Moreover, some women suffer psychological illnesses when they think of the aborted child and may be left infertile after the painful procedure.
If killing people is wrong and a foetus is a form of human life, isn't killing a foetus as bad as killing humans? Thus, abortion is wrong and should not be made legal to those who just want to get rid of the baby.
