Two questions, and the ignored but obvious answers

A father built a kingdom of beauty and plenty.
He protected and guided his children with love.
they thumbed noses at him, said
“We’ll do it our way! We need no guidance!
We are our own masters, what do we need you for?”
What's a father to do?
They were adults, then, though still young and foolish.
So, he let them go, with heavy heart.
He did not interfere. He let them try out their independence.
They went their own way.

Their grandchildren were many.
Some good, some evil, most somewhere in between.
Some read his letters and accepted his guidance,
But all suffered living in the world lead mainly
By children themselves, by lovers of themselves.
They ravaged the kingdom,
murdered, stole, loved, lost, wept and ranted,
wandered lost in icy storms.
When he offered love and guidance,
They again snapped at him and turned backs to him,
"What do we need you for? We are our own masters".
Then when their lives were rough,
They blamed him for letting them fall into such hardship
cursed his name for not bailing them out.

Should the father have raised an army of police?
Conquered in order to protect?
Should he have cleansed his kingdom of mutineers
And started all over?
If he had, would his right to guide ever be proven?

The children demanded to lead themselves, and so they shall
Until the question is answered and their endeavor fails
Or meets with success.
So that question never need be asked again
so such dark times never need occur again.

Still, I often see people ask
without desire for reply...
Inquire, in hopes there is no answer.
“If there were a God”, they say with disdain
“why would he allow such trial and evil?”.
Attempting to discredit a book they’ve never read.
Avoiding the truth of the father, left behind.

Because, naive children, he loves you enough
to let you live as you wish, to be your own masters.
If you would ask why he'd allow such a cruel world,
Then you should know, now, what we need him for
unless you simply choose not to see.
