Um, no... I read you have to kill the Mafia and the backstabber Lance.

I don't have a clue why he's a backstabber but that's what some of the walkthroughs say.

Makes the whole reason for killing Diaz go to hell, eh? I mean, if I had just stayed with him, I could have a huge army and fight Sunny and his dickheads. Unfortuanately, I did kill him and now I have to do all this shit on my own.... Gayness.
