If a friend stabbed his closest pal, he'd also be accused of murder. The United States Constitution says that murder is illegal. Killing the unborn is known as abortion. Many people say that a woman has a right to choose whether she wants to have the child or abort it. And literally, that is true, since the child obviously wouldn't be able to save itself.
Abortion is what some call a politically correct murder.
Politically, abortion is legal in countries of the world. But morally and ethically speaking, murder is murder. Stabbing somebody or having an abortion still leads to the same result. Unlawful and intentional death is murder.
