I'm one of those people who think he's dead but hope he's alive. When I saw the autopsy I knew that shit was fake as fuck so that gave me more hope. Plus, there's this ridiculous theory that he's coming back in 2014 according to the 7 Day Theory. A brief summary of it: When 2Pac released The Don Killuminati he went by the alias of 'Makaveli'.
Makaveli faked his death when he was 25. He came back when he was 43. Tupac came out of prison and started calling himself Makaveli and released the album The Don Killuminati under that alias. The name Makaveli can have the letters rearranged to spell Am Alive or I Am Alive. Tupac "Died at age 25, just like Makaveli. Makaveli came back at age 43, Tupac died at 4:03 PM=43. Some think Tupac is coming back at age 43, in 2014. When Tupac "Died" two days after his song I Ain't Mad Atcha came out, in that song he dies by getting shot coming out of a pop place... just like his "real death"
