It may be her body, but why does she have the right to destroy life, or the potential for life?
Because it's growing in her. Because it can't survive outside of her. Because she's the one who has to lug it around. Because of exactly how much of a change it will make.
If a woman doesnt want children, use protection or stay abstinent.
If that fails? If she's *****? If she makes a stupid mistake? If the situation changes? If she finds out that it's going to have severe birth defects that will probably result in its early death? If it's going to have a life-impacting mental illness that will require her to take care of it for its entire life? If its found that a previously unknown of hereditary disease the parents carried was passed onto that child?
It's far too individual. No one should have the right to force a woman to go through with a pregnancy that she doesn't want. It should be her choice. I'm all for contraception and giving the mother options to help raise the child. But if she doesn't want it, well, that's her choice.
It's not far to that life to say oh yeah i dont want you.
That life won't ever know. It isn't aware. At the time for legal abortions, it is not conscious. It has no social attachments. It cannot survive outside the womb. As far as logical thought goes, it is the equivalent of a tumor that will eventually become a member of society if carried to term. I'm not saying it's not human, I'm saying that there's more than enough reason for it to be the woman's choice.
Now, if there were a way to remove the baby without scarring and let it continue to grow somehow if the mother didn't want it, I'd be advocating for that. Abortion is the best option and has no downsides other than the regretful loss of another potential human being, of which this planet could do with less of.
As for the death penalty you didnt mention why it was not ethical.
Because there's always the doubt that the accused is actually innocent, or could have been rehabilitated/contributed to society in some way.
money should not be more important then justice.
Why is killing someone for killing someone else justice? Then you have two dead people instead of one, or more. It doesn't make anything better. Eye for an eye leaves the world blind. Often said, but rarely followed. We want to appease our sense of outrage. Capital punishment is like giving a medal to a dead soldier, comfort for the people grieving. It doesn't actually change anything.
