The Hamlet Project

What are these foul crimes of which Hamlet Sr. speaks?
One assumes his days of nature are his life (nice way to put it, Ghost King!)
so we don’t really have a ballpark timeframe for these foul crimes.
Foul crimes sound a lot more serious than just your run of the mill sins.
One assumes he has taken the Lord’s name in vain and other such pecadillos
But what does he see as his foul crimes?
He did some smiting of the sledded pollack on the ice – that’s possibly something –
And he is a king. Probably you don’t get to be or stay one of those without a little
Foulness. But what? What?
It opens the door for me to wonder what Hamlet’s father was like in life.
Hamlet says a lot of nice things about him – how loving he was to Hamlet’s mom,
Like various shining gods
But he has died before those things get said
and the bad stuff loses weight
(Or perhaps it is just burned away in the fires.)
