Why not? Let's remember everything Puffy has done.
1. IN COLLEGE...he over promoted a party and got multiple people trampled to death
2. He paid to have Pac killed or at the very least was associating with Keefe D who helped kill Pac
3. He sent Biggie out to LA a few months after Pac got killed knowing it was still hot and got Biggie killed
4. He flew back to NYC on the red eye, while Biggie was still warm, leaving everybody in LA after he goaded Biggie to go
5. He threw money in nikkas faces at the club, had Shyne shoot up the club to protect him, then left Shyne to the wolves
He's not a good person
I believe maybe 60-70% of what Cassie said
