I wonder if perhaps the argument could be made that indirectly Knight contributed to the final outcome by having involved Tupac deeper into the Mob Piru Blood/South Side Compton Crip fued & encouraging the escalation of it.
Of course Tupac ultimately made his own decision.
Suge was a terrible influence on Tupac. A good example of that occurred shortly before his death when he got himself a Mob Piru tattoo. Yeah, that's how fucked up Tupac was getting. Tupac wasn't from Compton, but Suge was in his ear non stop, filling his head with bullshit. This is the last guy he needed to be around, but it was ultimately his decision and he paid with his life. You know the first thing Tupac said to Orlando Anderson before he socked him was "you from the south?". That's typical gang talk. He didn't even mention that chain. I guess he wanted to show Suge what he was made of.
