It really all comes from where you grow at, and who you hang around with. And yes people change, change for the better. In pac case, he grew up rough, hard times arose, good times came, more bad times when those cowards in new york shot him( puffy, biggie, and all those other suckas) , hard times again, pac said prison made him worse, so he join with deathrow records, the planned was already in motion, good times again, rough times because people was trying to murder his name, good times again, pac said, everything was a game to him, its all for fun, las vegas came around, as i mention before the planned was already in motion 6 months or so in advanced, pac faked his death, and now living in peace with kadafi.
Again, it hurts to see the change like pac mention on pac's life.
