Why is abortion wrong ?

Abortion is NOT wrong. It is a piece of woman's health care.

I can't follow the logic of your argument. If no-one deserves life, then on what logical grounds can you conclude that 'a person shouldn't have to destroy their life...'?

Also, there's an equivocation in what you say. The sentences 'abortion would destroy an unborn child's life' and 'motherhood would destroy a woman's life', are not equivalent in meaning. The first means 'abortion would kill the child' the second means 'motherhood would affect the way the woman had to live her life because it increases her responsibilities'.

From the very moment of conception, a woman becomes a mother and a man becomes a father. At that point they both have responsibilities for the child they have created. Neither of them has the right to betray that child - either the mother by aborting it or the father by abandoning it and shirking his proper role in the family.

I don't consider it to be wrong. I wouldn't have an abortion myself. That's my choice. I wouldn't EVER tell another woman that they shouldn't. That's their choice. Their reasons might be different to mine so I wouldn't judge.
