the character of Dumbledore in Harry Potter universe : is most complex..
...Dumbledore : saw 'good' in Tom Riddle..
taught him : created 'him' - Voldemort..
akin to devil ...
and its worshipers..
in logical flow of things..
Dumbledore made the most expensive mistake ...
which killed his school and many of his students..
But He also created Harry Potter ...
he is an allegory of god...
