I didn't even made an argument. "To kill" means somehow causing the death of something. This the fact. It doesn't matter if its a animal or a human. An certainly doesn't matter where it happens. You can kill something/someone on purpose, by accident or "involuntary on purpose" like in self defense but that doesn't change the killing part. You caused the death of something = you killed. Facts are neutral. I'm not saying chicks should or should not be killed whether inside the egg or outside. All I'm saying is that it is without any doubt killing, therefore the "no-kill" thing is a lie. Killing an embryo inside a human obviously is killing to. There is a special word for that but that doesn't change the facts.

Also I assume with "embryo" you meant a "human embryo" so by definition it is already a living human (assuming its not a dead human embryo). Its a living humans it a early development state that we call embryo it will become a living humans fetus and so on unless it dies or gets killed. These are the facts, words have meanings and definitions. Thats why we can not kill SARS-CoV-2 with bleach because by definition viruses are not alive so we can not cause its death)
