Is abortion basically the same as killing a person in coma?

But the difference is that the coma person can be there forever. While a baby can be given birth in about some months. Of course its logical to take abortion if the mother's life is in danger.

But since baby's heart pumps blood in about 21 days. Its sorta alive. It just don't have a nervous system or a consciousness yet. Sorta like a person in coma is like. It doesn't have consciousness or feel nerves. It just lies there in sleep. But unlike that person in coma and the baby, the coma person can lay there forever, while a child can be given birth.

So its more the alternatives: Either i can wait, or i won't waste time on it.

So i am simply a fence sitter basically on this.

Kinda just dug this info on development of a fetus.

What's your opinion?
