I didn’t say a person who kills a newborn shouldn’t go to jail, I said their crime shouldn’t be murder. Maybe something like theft? Because they are stealing from the parents of the newborn
You’re reading right, I don’t think humans become people until consciousness develops. 1 year olds aren’t yet aware of their existence, and their minds are not at the level where I would consider them people and worry about them being killed any more than I worry about animals being killed.
My thinking is that consciousness makes a living thing a person, without it, it’s not a person and I don’t worry about killing it. 7 year olds have consciousness, the unborn and newborns for example do not. Still, if you kill someone else’s newborn without their consent, you are destroying a baby they spent 9 months producing, may have spent even more time and money trying to conceive. It is a serious offense against them to destroy the newborn
I think to a point a child’s “value” does increase with age. I wouldn’t feel too sad for example if a young child died, because that child doesn’t really have a mind yet, doesn’t really understand life, dream of the future and so on.
