I feel like saying "preventing a life" is just a use of languague to comfort yourself from that act.
you believe it should be legal and okay to do it, but you want to change the language of what it is so it doesn't sound as bad.
If somebody is dying and they need some type of medicine, and you have the power to give it to them, but you don't or you prevent them from getting it, then you're killing that person in my opinion.
It doesn't matter if this person was gonna die from a car crash or a random event before that happens, you still took action to prevent a life from continuing, and to me that's killing someone.
Same thing with abortion.
