There is exactly one circumstance where without any additional action on the part of the child it is permissible

If you know another member of the family will attempt to honor kill them aka to protect them and in that case you will need to still support them but if it's to get them safe from a monstrous member of the family that is the only acceptable circumstance furthermore this should be a temporary thing while you get a safe way to be with a an away from the monster or some family member

You guys might think this is ridiculous thing but you got to remember there are multiple countries where they will be executed so if it's to protect them in those places then you need to do what you need to do
