It implies that the right thing to do is to act against one's own will instead of as one wishes. It is a nasty word for something good. People should act in accord with their own wishes. The purpose of this list of words is to justify their coercion of the child. Note that the use of this word implies that these parents invade others' privacy.
Privacy is vital for the healthy psychological development of any child.
That the parents are using these particular words, loaded as they are with coercive and, in my view false, premises, must mean that they accept the premises upon which these words rely. The only possible reason to use these words is to justify coercion. The parents are listing all these ghastly things to convince the reader to agree that the situation merits discounting the child's own preferences and happiness at school. Perhaps they don't recognise it as cruelty because they consider riding roughshod over his wishes to be perfectly justified, as they have and are arguing. Most parents think not, of course, but I'll bet that they would feel differently if it were they who were on the sharp end of such coercion.
