Sounds like a suicide note from a distraught individual to me, leaving aside the lack of Satoshi's grammar. I do not know enough about his background to contact the police for a well-being check; does anyone here?
At face value, I would agree. But given that he's clearly lying about being Satoshi, and therefore also lying in this note, I figure it's likely that the "suicidal" tone was deliberately chosen. It's just another attempt to stir up controversy.
That's a very serious thing to say in regard to something you know very little about.
