Wasn't Pac told by multiple people that Big and Puff set him up? While he was in prison?
That's where the killuminati shyt came from, or so I heard. I don't think Pac lied on purpose. He probably got false information and ran off emotion. After Who Shot Ya, his paranoia took a life of its own
If Pac in his later years moved levelheadedly, thinking with his emotional and logical mind, he wouldn't have made that beef get out of hand
He should've had better people around him too. Death Row was the last place he should've signed to. It's way deeper than a "lie". Suge and them probably egged Pac on to go at Biggie
