I believe that abortion is right. I can't see why feti should have the same rights as born human beings. If I was to think abortion was wrong, I wouldn't eat eggs (yes, I know, but we have our own hens and a rooster, and we can't be 100% sure that the egg is unfertilised).
However, I believe that during the later stages in the pre-birth development, it would be wrong to kill it, since it's pretty much an infant then, but is abortion possible when it has developed that much?
I don't get why some people believe it's wrong to kill undeveloped feti, but not animals outside their mothers. I'm not sure where to draw the line, but certainly, I'd compare undeveloped feti to plants or oysters, due to their passive nature.

Why bring a child to life if it is not wanted?
