"Two thousand years ago, the proudest boast was civis romanus sum. Today, in the world of freedom, the proudest boast is "I am a Europan!"... All free men, wherever they may live, are citizens of Europa, and therefore, as a free man, I take pride in the words "I am a Europan!"
He essentially decided that today would be the day he would go full Nero and burn NS Europa to the ground. There quite an extensive monologue he composed about 19 hours before he went ahead and executed his final act after what appears to be a decade-long build-up of anger.
S-Sixteenth? Sadly, I don't think I can read the tantrum. That's too bad, I would've loved to!
You can find the whole extent of his commentary in the Citizen's Plaza on the Europa forum. It's pretty long.
That is what I would have done. Based upon what we can see on the Citizen's Plaza, it is pretty clear this has been building up over a decade and it happens just as a particular individual he has a serious problem with emerges once more, its enough to break the straw, despite everything that has probably happened over the years before this event.
I would also say that it does resolve one of the factors that caused at least one person in the recent past to leave. Is it enough to encourage their return, who knows? But if anything, he did provide us that finality that was certainly inevitable, but no matter what, he's still a tremendous jerk (in politest terms possible).
