How the hell was it mutual? why do you think they started Damageplan( to end Pantera) they had a new frontman, a new band, and record contract. Dime and Vinnie said they would never work with Phil again right before the murder, they hated Phil to death befor Dec 8, 2004 and still does. Pantera would of never broke up if it wasn't for Phil and his desires to start crappy bands like Superjoint. If Pantera never broke up Dime would probably still be alive because they wouldn't be playing little shitty clubs like the Alrosa.
I don't particularly care about the politics surrounding the breakup of Pantera. I do have to comment on your belief that Dime's death was a direct result of Pantera's breakup. That same logic would mean that any car accident I have on the way to work is the fault of my employer. If they let me work from home more often, I wouldn't have gotten into the accident, right?
I can see a grief stricken relative making the above statement. We as fans, should be seperated from the situation enough to be a bit more rational.
