One answer to that surely has to be: not with any easy consensus. The fact is that, even in these hours after Green being booted out of Rangers for a final time, many are still disputing his true worth to the club.
Green has by no means been an unqualified disaster at Ibrox. When the 140-year-old club lay in ruins in the spring of 2012, he stepped up, taking his chances where others could not, and aided Rangers' rebirth.
Some today are glibly calling Green out as a shyster and a "money-grabber" but that is to ignore the grievous reality around Rangers 14 months ago. Few wanted to take the risk. Others - like Bill Miller - took one look at the figures and ran away.
The Blue Knights, those perennial near-heroes of Rangers, talked a lot but lacked in substance, money and conviction. Various other parties postured but failed to produce.
Amid this hot air of would-be saviours Green came forth, put other people's money where his mouth was, and closed the Rangers deal.
He got the dissolved club's assets for a snip but also ran quite a risk. He then orchestrated the flotation of Rangers International Football Club and raised an estimated £22 million.
Not bad going, I say, given the paucity of people either willing or able to step into the mire of the club's liquidation.
In truth, few people have held both a perceptive and consistent line on Charles Green. There are quite a few Rangers fans today who are lynching his back as he is chased out of town, who not so long ago were keen Green advocates.
This was a guy who was willing to take on everyone - the SFA, the SPL, the press - and many a Rangers fan swooned over him. "I like his style, I like the cut of this man's jib," was a common refrain of last autumn and winter.
Well, no more. In a few short months it has quickly become a case of "Charles, f*** off, we don't want you here," with scarcely a revisionist blink of an eye.
Green was also grossly culpable. Probably the single most heinous piece of incompetence this Rangers board has achieved is the squandering of up to £25 million in the past 10 months.
Green now likes to claim that he is appalled by this incompetence, but he was the Rangers CEO for a substantial period of that time, and thus surely a man who set the financial course.
On top of that came all his verbal idiocies, none of which I need to re-visit here. Suffice to say there was one very perceptive voice from England who said in June 2012: "Charles Green is capable of a lot of things. But one thing he won't be able to do is control his big mouth…"
Actually, it is not his deeds, but his words, which have led to his Rangers hounding. By his deeds alone I believe Green could have survived in Glasgow. But his words - exaggerated, absurd, and occasionally peppered with unintended racism - turned enough supporters against him to set in motion his departure.
A golden opportunity has been lost at Rangers. The club, with a more realistic budget in the fourth tier of Scottish football, could have put down a template based on young players and more modest salaries, while still relatively easily climbing through the divisions back to the top.
Instead, through yet more financial recklessness, some, like ex-director Dave King, believe Rangers is a busted flush all over again, and will need fresh tranches of investment magically plucked from somewhere. There is even talk of a further share-issue being an inevitability, given the financial mess of Ibrox.
As I write, various Rangers characters, like current CEO Craig Mather, are desperately clinging to the wreckage. Mather, scarcely before a CEO in his life, has an uncanny knack of siding with anyone who might throw him an Ibrox lifeline: Ally McCoist, Walter Smith, even James Easdale.
The one man he suddenly isn't siding with is Charles Green, the figure who brought him to Rangers in the first place. No, that wouldn't do, because Green is now persona non grata, and Mather knows what "tarring" and "brushes" are all about.
Green must feel betrayed by a lot of people. Comfortingly, in this tawdry tale of Rangers muck-raking and men on the make, perhaps £2.2 million of personal profit from his shares will soothe his pain.
In that regard he's done well, the Yorkshireman.
