Maybe he was thinking about 2pac and Biggies hatred with each other, and he thinks (so do I) that they were (possibly) killed in retaliation, as in Death Row beat up a Crip (I think thats right), that Crip told Biggie, Biggie ordered the hit on 2pac, Suge ordered the hit on Biggie. In my opinion anyway. So he made this rap so it doesn't happen again in todays hip hop world as there's too much rivalry going on.
