“L’enfer est plein de bonnes volontés et désirs.“ (Hell is full of good wishes and desires.)
Saint Bernard of Clairvaux
Klaven reminds us of something that is very true in the above video. In human affairs someone who, from the outset, intends to do evil can cause quite a bit of calamity and tragedy. However, for true catastrophes you generally need someone who is seeking to do good, but is blind to the negative consequences of his actions. History is replete with examples. Martin Luther, I think, really did start out honestly intending to merely give impetus to reform within the Church. Gandhi did not want to see India divided once the British withdrew because he honestly believed that Muslims and Hindus could live in peace together throughout the subcontinent. Neville Chamberlain resisted taking any stand against Hitler until September 1939 because he honestly wished to spare Britain another World War only a generation after the first one.
