Infanticide, would be seen by most of us in the first world as evil - though there are many ethical reasons why it would be acceptable in historical civilizations where the addition of a new child could result in communal risk/starvation (Think tribal societies that were on the edge of survival - not really relevant in most societies today, and certainly not in China).
But, is forced sterilization evil, per se? Or is it just our western cultures sense of what is right and wrong?
Where do you draw the line, and do you accept that a country has some right to control it's population through mechanisms such as penalties for second children, withholding government care, etc...
I'm really quite interested in knowing where the debate lines are drawn with this.
