Arturo, How Could You Be So Stupid?

You believed Enrico when he said Lucia was mourning her mother,
And while you had an inkling that she was longing for another,
You thought that you could could win her over with your wealth and your position.
Without even giving a thought to her emotional condition.

Arturo, how could you be so stupid to not see her countinance?
If you had, you'd still be alive with prosperity and abundance.
But you didn't, and it's really no wonder you lost your life.  
Because you didn't fully grasp what was wrong with your new wife.  

Then again, how could you know that the woman was being abused?
And that she was, to save her brother's failing fortune, was merely being used?
And then again, you couldn't predict that she would go totally around the bend;
Nor could you expect that she would bring about your end.
