IT’s not a viable human until 24 weeks in any practical sense toward survivability.
it is an alive and developing human organism from the moment of conception with no possibility of being conscious of self as a separate conscious human being during the fifteenth week..In a pregnant woman’s body at fifteen weeks there is only one neurological functioning human being. One cannot murder a living human organism that is not capable of being separate thus equal to the human being that has decided to end its development or if you prefer surgically or pharmaceutically “kill” it.
When a woman kills it before 16 weeks more importantly there is also no harm to a victim outside of her body. No viable human being victim of violence exists.
