NO King gains his throne "peacefully". You have to go to war, take that shyt, and write your legacy in blood. In recorded history there have been Sons who murdered their own fathers, Uncles, and brothers over the right to the throne. Hip Hop is no different, a humble leader will be seen as a weak leader at some point and another MC will come for blood. You don't have to be 50 Cent and diss the entire industry but you DO have to let it be known that you are ready and willing to lyrically snatch souls from bodies. EVERY top tier MC has at one time proclaimed themselves the best and had to battle for that title, whether it be directly or subliminally. This is part of Hip Hop and Kendrick understands that, he even went out of his way to extend an olive branch of sorts to his competition and let them know how ill he thinks they are. Can you IMAGINE Nas or Jay-Z or Wu-Tang extending olive branches to rappers back in the day that they felt were competition? Life long relationships were ended over Hip Hop competition. Nas and Biggie had a brief falling out. Ghost and Rae dissed Biggie while Biggie was showing love to the Wu having Meth on his first album and trying to get production from RZA. Jay-Z, Ja, and DMX couldn't record an album together because all three of their egos wouldn't allow it. Nas and Mega engaged in a lyrical battle for the better part of a decade and they GREW UP together. Hip Hop both builds and destroys, dynasties are built from the street corner straight up to the offices of label conglomerates....
It's One life, One love, so there can only be ONE King....
