When a demon cries

Just a thought I had the other day.

What is rain?
They say it is the angels crying.
Their tears cold and many with sorrow.
But when a demon cries
what happens?
Could it be that
since we consider them evil
we never cared what happened
when a demon cries?
But what is evil?
Is it a thing
or an emotion?
A psychology
or a state or mind?
Perhaps if we knew
what evil truly is
we could understand
what happens
when a demon cries.
