Is pro life a lie?

I read a comment from someone stating pro-lifers are actually pro-birth which is not the same thing. It started me thinking. If a person were actually pro-life that would mean they would have to be like a Buddhist. Every life is valuable. From animals to humans. You wouldn’t even carry a gun or any weapon to harm another human being. You wouldn’t believe in the death penalty because even a murderer’s life is valuable. So back to my main question. Is pro-life a lie?
