good triumphs over evil because.....well, good is just stronger than evil!That may be a philosophy, buy it is not the traditional D&D one. Celestials and good aligned creatures were almost always more powerful than their evil counterparts during the TSR era (look at metallic vs chromatic or angels vs devils in the 1e MM1 & MM2). The idea was the more powerful good creatures fend off the much more numerous evil creatures.
Its like back in 3e you looked at the book of vile darkness versus the book of exalted deeds. ED was WAY more cracked! Good is just broken
