I think leaving your baby in the woods to die is wrong, but it doesn't violate NAP necessarily.
I would consider this a violation of the NAP if the baby was under the care of the person who left it there. There’s an implicit contract between a voluntary caregiver (
e.g., parent) and a helpless child, thus, abandonment is a contract violation: a violation of the NAP. However, a disinterested third party coming across an abandoned child, and leaving it abandoned, whereupon it dies, hasn’t violated the NAP, because he wasn’t responsible for the baby to begin with.
But, this debate’s been had elsewhere on this forum, the only difference being it was about leaving a baby to
drown, so I don’t want to repeat everything that was said there, here.
