The stories of bands falling apart are so alike sometimes, likewise with falling marriages I guess. I always compare DS to The Police (they emerged from the same region at the same time and both had prominent singer-songwriters occupying 80% of the exposure). For how different they were as a band, having practically no lineup changes compared to constantly changing DS, but severely battling over mutually written music material, their fate is all the same.
The lead man wants to do it on his own and burn all the bridges. I think compared to Sting, Mark did it better and dealt with his mates better, however, Sting learned earlier he should go his own way, and DS shutting down earlier would benefit its legacy (in my humble opinion). Also, like Sting, Mark resurrected DS for a tour or an album and in my view too early. And doing it again would be a farce as in the famous quote, "History repeats itself, first as tragedy, second as farce".
