There are several drawbacks, apart from the destruction of human embryos which would necessarily happen during prior experimentation. The process is very risky. Many deformed lambs were produced in the making of Dolly the cloned sheep. Cloning would confuse family relationships harmfully, the baby being genetically the sibling of the DNA donor. Yes, we are against the deliberate ending of any innocent human life right from its start when a sperm and an ovum unite to make a new human being.
Abortion is also harmful to women, who often regret it and suffer in mind and body.
We do not judge or blame or condemn women who have had an abortion. We understand the pressures, the lack of accurate information and support and time to think clearly, which may have led to a rushed and often bitterly regretted decision. Very rarely an operation to save the mother's life, such as the removal of a cancerous womb, or a damaged fallopian tube in an ectopic pregnancy, must inevitably result in the unwanted side-effect of the baby's death. This is very sad but it is not an abortion, it is not the deliberate ending of a life, it has never been illegal, and no one is against it. In other, still rare, cases, doctors may be able to save mother and baby by letting the pregnancy continue until the baby can survive outside the womb.
