Life always leads to death.
Birth leads to life.
Conception leads to birth.
Parents are responsible for conception.
Ok.
Ergo parents are murderers of their biological children.
Pure logic.
Prove me wrong
There's an invisible fairy on your nose, prove me wrong. You can't, just like I cannot prove you wrong. However, I can provide pretty sound refutes to your argument.
Murder:
"Law. the killing of another human being...."
Killing:
"the act of a person or thing that kills."
Kills:
"to deprive of life in any manner; cause the death of; slay. "
Deprive: to remove or withhold something from the enjoyment or possession of (a person or persons): to deprive a man of life; to deprive a baby of candy.
Life:
"the condition that distinguishes organisms from inorganic objects and dead organisms, being manifested by growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally."
What I understand from your argument: Parents, by having sex give life which inevitably leads to death thus making them murderers.
Yes, you can argue that all life leads to death. However, when you state that parents are murderers you debunk your argument. Your argument assumes that the action of dying is what deprives someone from living. That is false. Death, like darkness to light, is the absence of life. It is the term used to describe the cessation of living. By having sex and conceiving parents give their children life BUT just because that child's life leads to death does not mean that parents are murderers of the child. In order for parents to "kill/murder" their child the life of the child has to be deprived; it must be removed or withheld. Death, is not the action of removing or withholding life. It is the result of a removed or withheld life.
