Answer: The flashback to Jesse and Jane helps remind the audience of what happened to her. That informed Jesse's decision to try and stop Andrea getting high.

Answer: The corpse was old and he was around people he knew. Seeing a severed head walking around on a turtle was just too much for him.

Answer: Hank is very emotionally vulnerable at this point. He'd just had an intense shoot-out with Tuco that affected him more than he is willing to admit.

Answer: The FCC actually only regulates local broadcast channels. Cable channels - even basic ones - are free to depict as much violence, profanity, and sexual content (as long as it's not pornographic) as they want. However, they choose to scale back on that so as not to offend viewers and potentially drive away sponsors.

Answer: In an episode of Better Call Saul, we see Gus prevent someone from murdering Hector, and even pay for some of his treatment after Hector has a stroke. He wants Hector to remain alive in the state that we see him: bound to a wheelchair, unable to speak, unable to take care of himself. It's Gus' way of making Hector suffer. He felt a quick death would be letting Hector off too easy.

Answer: Gus considered killing Hector as being "too good for him." He wanted Hector to suffer in the same way he had suffered. Hector killed Gus' partner, so Gus worked to destroy Hector's family before gloating and killing him. Gus even prevented Mike from killing Hector for this very reason.

Answer: Because for as long as Hector was alive Gus could gloat over his enemy.

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: He originally wanted him dead but over the year or so he was on the run he lost his family and his money and realised the horrible person he had become. He thought Jesse was already dead but when Pete and Badger told hi the blue meth was still in circulation he realised Jesse was being forced to cook and decided to save him because he was no longer the ruthless Heisenberg but was now back to being Walter Whiter.

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.
