On the one hand, there are people who think that it is right, because you're not killing a human, it's just an embryo, a group of cells, so women have the right to decide if they want to be mothers or not. For example, when there's a violation and the woman becomes pregnant.
On the other hand, people who think that abortion isn't right are usually very religious. They think that women are killing their babies, and killing people is illegal. Not only do they think that, but they also think it's morally incorrect. In Spain, now abortion is not allowed, and people have done a lot of protests.
Taking all this into account, from my point of view, I believe that abortion should be allowed, since women who want to do it, will do it illegaly, so there's more probability of death, because illegal clinics have no control.
