Charge the lunatic with attempted murder and ask him to fly German Wings next time he want to commit suicide - better chance there ...

You are a sick person!

Impossible to open in flight. But having a troubled individual on a flight can be quite disconcerting.

He may at 10,000 feet. I used to fly in planes non-ressurised in the Middle East at that height. May be impossible in a 737 though I am not sure

My thoughts as well. Not that much of a pressure differential at only 10K ft. But OTOH not sure it takes much of a diff'l to hold it closed. But even if he did get it open it's not like there'd have been a catastrophic and lethal depressurization.

Decompression at that height apart from being scary for the passengers would not be catostrophic

Isn't that what I said?

Well there is one that slipped through ISIS fingers, or they would have laid claim to that as well.
