I personally think that a first trimester abortion is not really killing a child as much as ejaculating your semen outside a vagina or having your period is not murder as those cells are not yet a person. But I absolutely understand your sentiment and I think it comes from a good place and kind heart. That's why this is such a hot button issue for disagreement.
I believe there might be a lot of legitimate reasons to have an abortion. Here's a horrifying story about an abortion ban that has led to a great deal of unnecessary physical and emotional suffering.
That said, I see a lot of people coming to abortion because of irresponsibility and ignorance. I hope that if you are against abortion you are surely for safe sex and contraception right? Those are the things that can prevent abortions before they happen.
