I'm going to take my opinion one step more, just so you can all know fully what I believe.
Under NO circumstance do I believe an abortion is ok, period. Whatever the circumstances that the mother and father are under, it in no way should decide if a living being is denied of life, a life that each and every one of us here share.
Is it the childs fault that it was the brought forth by a rape? Of course not, it didn't have any say in the matter. For those who are rape victoms, having an abortion will not wipe away and clean your mind and soul from the horrible thing that has been done to you. When you try to say abortion is ok if someone has been raped, it is simply another case of someone being blind, and looking for a way out of an uncomfortable situation.
The cycle goes on all over the world, a man is trobled in his youth by someone (I know it's not always the case), he grows up troubled and commits the horrible act of rape on a woman who then get's pregnant, and from there the pregnant woman decides to have the innocent child growing inside of her put to death, in hopes that it will end the cycle.
It will not though, the cycle of innocent killing, the hurting of innocent people, the cycle of being horrible to fellow innocent man will NEVER end through the means of that very same killing of an innocent, that very same hurting of an innocent, that very same being horrible to an innocent.
The only way to end the cruel cycle, is through the love of God...God himself.
The best way to end the cycle, is to give a CHANCE at life to those you never had a say in the matter. If the poor mother who had such a horrible act done to her does not feel that she should nor can, take care of the child then there are plenty of loving and adoring familles out there who would love to take that very child into their home...to give that child the love, God.
The ending point, as I said, is that a growing child has no say of it's own. A growing child is innocent, one of Gods children, an example of pure love. To snuff that very love out, to end a wonderful thing, is hurtful to so many people, and unfair to the child.
Through acts of violence and horrible acts, examples of love can come forth. A child is the one of the most ultimate examples of love that we have here on Earth.
You don't want me to get into the topic of rape itself.

While I believe that no harm should be done to innocent people, and especially children, I am all for the punnishment of the wicked, the punnishment of those who do the harm to the very innocent people that I'm talking about.
Also, I obviously believe that women (and men) have choices to make, and that they should be allowed to make those choices. The choice is weather they should have sex in the first place, to chance a birth which they might not want. That is the choice that everyone must make, but once you make THAT choice, be prepared to deal with what could happen. Go ahead with the action...but understand the possible reactions as well, and be ready to accept whatever may come.
