I believe abortion is OK because a fetus is not a living human. It has no brain, it can not think, it can not feel emotions like love, hate, compassion, anger, fear, etc. It is not even aware of it's own existence! It is life, but it is not alive. The life and well-being of the woman is far more important than the life of the embryo. Scientifically, a fetus is a cancerous growth. Removing an embryo is no more immoral than removing a cancer tumor. Ruining somone's life with an unwanted baby IS immoral. Cancelling a pregnancy is not.
