Contradictions

Why is dark evil and light good?
Why is cold dark and warmth light?
My world yearns for dark and warmth;
Aren't people composed that way?
We say don't judge a book by its covers, yet
Why isn't light seen as a façade for the
Shallow depths concealing cold, calculating minds?
Why isn't dark a measure of depth,
Or calm, tranquil nights?
But the sun will always be worshipped,
And the moon will lead her solitary life
Causing all lonely souls to cry out in sympathy
