I just see it as a more realistic balance between conflicting interests.
Balanced? How? To be balanced something must have an equal distribution of weight, or figuratively the different elements of a conflict or problem must be roughly equal in proportion.
Neither the personal interests nor the potential solutions and potential risks are 'balanced' in the case of abortion.
The interests of the unborn child are primarily continued survival, continued healthy development, and continued safety. The mothers interests are primarily non-survival related: convenience, finances, independence, social standing, etc.
[Only a very small fraction of mothers seeking abortion could be said to have their survival directly threatened, and the majority of those cases would not need abortion as a solution vs. medical treatment which might have a side effect of the child dying.]
So, 'on balance' the interests of the child are superior since they directly relate to the basic needs of survival and not to hardship or convenience.
The potential risks the mother faces by having the child: loss of social standing, loss of free time, loss of finances, loss of independence, potential loss of relationships. The potential losses the child faces if the mother chooses to abort are: near certain death, pain if past as a certain age, potential disfigurement, disability, or torment if the abortion is botched.
On balance, again, the child's risks are directly related to survival whereas the mother's risks are to convenience & lifestyle.
Furthermore, the mother has ways to ease any hardships or inconveniences (local resources, seeking help, adoption, etc.) The unborn baby has no way to stop an abortion.
So, the situation is hardly 'balanced' at all. The person with the most options and the least important needs is given complete control over whether or not the person with the most important needs and no options will die or not.
