Can you give any everyday non-religious examples of Evil masquerading as Good. Something down to earth that I can relate to?

Two examples come to mind quickly. First, the loving, caring but overdulgent and compliant parent who provides a child with everything it could wish for, never chastising or disciplining, wrongly believe that the child will thus have happiness, freedom and freewill to develop along its own path. Superficially what the parent is doing appears to be good, the intent is certainly good within its limitations. However, almost invariably the end result of this ‘good’ is an unbalanced, irresponsible and self-centered personality. What is ultimately contributed to the world is something more akin to Evil. The other example is certain welfare legislations aimed at ‘freeing up’ marital and domestic restrictions. The concepts of such legislations appear to be good, but once the superficialities are brushed aside some very sinister aspects are revealed. The legislations in fact contribute to marital discontent and are conducive to many domestic difficulties and to the breakdown of family life. Here we have a case of something actually conceived in good intent and with the best of motives by the legislators themselves, but in actual fact the latter are no more than pawns in a greater game than they can comprehend, which is the culmination of a grim struggle which has gone on over the generations. There are religious teachings about the struggle between the Sons of Righteousness and the Sons of Wickedness, between the Children of Light and the Children of Darkness, between God and Satan, Good and Evil, all of which seems to lead up to some grim day when the issue will finally be settled.
