BUT assuming everything goes alright and no one interferes with it's development it WILL become a baby.
If eggs do get fertilised, what makes you think they will result in a dead embryo?
Because, as you among others conveniently ignored, fertilized eggs do result in a dead embryo 98% of the time, and a dead fetus about 1% of the time. Only 1% (or possibly less) of actual fertilizations and embryonic development result in a living, breathing child at the end of the gestational period.
You want to talk about killing people after 20 weeks gestation, then you go right ahead, but by every means that we actually define a human life a developing embryo is not even remotely a person until at least that point.
However, as Mefustae has been reiterating over and over, this is a contentious issue and the debate is not going away. In the absence of social consensus, reasonable, progressive, democractic nations err on the side of human freedoms and provide freedom of choice to human beings who we KNOW exist and we KNOW are going to impacted by the decision, rather than relying on the what-if factor.
Morally, I don't agree with women using abortion as a simple, ordinary means of birth control, but:
1. That case is rare anyway; relatively few abortions are the result of an ordinary accidental pregnancy.
2. I wouldn't dream of letting my personal morals directly, significantly, and continually impact the individual lives in which I have no stake.
I notice nobody bothered to address my points on how the organizations that are the biggest anti-abortion advocates kill fully developed adults and children on a daily basis either. I'd like that hypocrisy explained somewhere if you want to keep going on about how wrong it is to kill embryos.
