From a moral perspective I am against it. However, from a practical point of view, I am with it. So therefore, I AM WITH IT
Although I do believe you are ending life, I think it would be far worse for a baby to be born into a situation where it is not wanted. Usually, like in the U.S. for example, the baby would be born into a lower income group to a single mother, who won't do a good job of raising the child in the first place and providing it with a normal life.
Also, there is evidence to suggest that the legalization of abortion in America eventually led to the lowering of the crime rate, but I won't get into that now.
