Dough was jealous of Ricky
he was the black sheep
It wasn't just that.
He hated that Rick didn't see what made him special.
He hated that Rick didn't realize he was the favorite.
He hated that niggaz thought college was just to get bitches. He felt niggaz should go there to learn.
He hated that Rick ain't take the family shit seriously. Right before they fought dough called Rick's baby mother his wife. Rick played it off and dough says. " Might as well be, y'all a family"
And he scolded the niggaz on the porch when the recruiter came....
Dough wasn't simply jealous..... He was bitter that people like Rick who lived under the same roof with him didn't take seriously how insignificant they were to the rest of the world.
Dough was dropping knowledge the whole movie. The speech at the end about how all the shit in the news, and nothing about a top college prospect being killed. That should have been major news.
He just wanted his people to do better. He wanted Rick to be better than he was. But Rick fucked up by being killed.
That's why dough was so methodical about killing Ferris. He was hurt on multiple levels. He didn't care about being caught, because he knew his life didn't matter. Rick's did though. Rick could have been great. So dough wanted to make sure he executed everyone that was involved with Rick's death.
And that's why he never faulted Tre for getting out the car. He wanted Tre to be great as well
