One interpretation of the universal theme in 'The Diary Of Ann Frank' is the way her book survives forever as a lasting testament to the idea of 'Good.' Yes, evil was seen to win out against Ann's family and thousands of others throughout the world in the short term, but Ann was blessed also to see good done in her short lifetime - sacrifice,risk,offering refuge,moral support and kindness. Sadly, in the end these small and great acts of bravery weren't enough to save her but they happened and shine out as beacons forever in the fight against power corruption and evil. This is important because humankind needs the concept and emotion of 'Hope.' Without it, we would be consumed in a whirlpool of despair and never have the courage to stand up against tyrants. In the end, evil always hurts it's perpetrators as they are like scorpions boxed into a corner and stinging themselves to death - they damage their own personalities/souls. Ann's diary as a testament to the power of good versus evil in terms of infinity,not just the short-term of a life-span, stands out in it's incorrigible and bright presentation of the truth of the good that is in humankind.
