Answer: Part of reason for the firing was because George considered Gus a personal friend and ignored Hank's suspicions of Gus' involvement in the meth business. Even after questioning Gus, he still ignored Hank when Hank try's to tell him Gus is lying.

Answer: The DEA needed a scapegoat to throw under the bus as Gus made them look bad being right under their nose and George was the agent in charge so took the fall. And yes, had Hank not been killed he too would most likely have been fired.

Answer: Walt does use Lilly of the Valley berries to poison Brock. Vince Gilligan said he and the writers imagined Walt went to Brock's school with a poisoned juice box (there's subtle clues to confirm Walt knew what school Brock went to). But, when Jesse went to Saul's office, Saul's bodyguard, Huell, does a cigarette pack swap on Jesse when he pats Jesse down. Now the cigarette pack Jesse has no longer has the vial of ricin in it and Walt tries to convince Jesse that Gus stole the ricin and used it on Brock.

Chosen answer: There are several possibilities. Gus primarily does it to make an example out of Victor. Victor is one of Gus' most loyal henchman, and yet he had no problem killing him. Meaning it doesn't matter how loyal or valuable Walt is, he can still be killed and it won't bother Gus. However, Walt tells Jesse that perhaps Victor "flew too close to the sun." Meaning, Victor over stepped his bounds by learning how to cook meth. Gus didn't appreciate Victor's initiative and Gus only wants his employees to do the job they're given. Again, telling Walt and Jesse to do their job or else.
