All of this is true however, the initial origin of the beef is all Pac. Biggie and Pac beef only started because of Pac. Literally he was the main the culprit and caused the tension, whether or not Suge put the battery in his back or not, if Pac says nothing about Biggie, there is no beef. Pac was acting like a lunatic. Biggie didn't handle it great either (Making the diss records, going to LA months after Pac's death) but him being pissed at some guy that was suppose to be cool with him, dissing him, because he has this big conspiracy theory shyt he made up in his head and through hearsay, makes sense. Pac could've merely talked to Biggie and get his side but instead chose to run with emotions, forth hand info from jail house snitches and Suge Knight
