Abortion is wrong in every instance. No matter what the circumstance or incident that has occured. People say it may be a right excuse when the girl has been raped (or similar situations) but it is always wrong (even if you became pregnant against your will, adoption is always a good choice). This is because abortion is murder. Murder is wrong and I am sure everyone here believes this. However, the debate settles in when you come to believe that abortion could NOT be murder. It IS murder because it is killing without appropriate reasoning. KILLING IS DIFFERENT THAN MURDER, KILLING CAN BE MURDER BUT KILLING IS NOT ALWAYS MURDER. I will now explain how killing cannot be murder, which is very simple. In war, a just war, killing is rational because it is defending what is yours. Also, self defense, accidental killing, and hunting (for food only) can all be justified as just killing. This is simply scratching the surface of how many ways killing can be justified as an appropriate act.
An example of where people don't understand how abortion really is murder, is in England. In England, it is illegal to beat your child. However, it is totally legal to abort your child.
And about the talks of weeks, days, months, ect., this does not matter. As soon as the human is being formed at all, they are human enough to have a soul and, thus, be human. Making Abortion murder.
From this, you can see how simple this discussion could be if people would use common sense. ABORTION IS MURDER! NOTHING WILL CHANGE THAT.
