I hate abortion I think it's demonic

I don't know how to explain it but abortion makes me sick the idea of my body my choice is just so selfish I don't understand how some Christians agree with it killing an unborn child is a sin I've been watching and reading about it the whole day I understand that it's difficult in cases of rape and assaulted but it's not the baby's fault that you were raped if you can't put life into your own body what gives yoh the right to take it?
