Question: Why did everyone completely ignore Penguin biting a man's nose off?
Answer: The same reason real-world employees might not say anything if their boss is abusive or inappropriate - they want to stay quiet and keep their jobs. Best not rock the boat, so to speak. Also, both Penguin and Max Shreck are very influential people - not exactly the sort of people you'd want to mess with or contest. Hence, everyone sort-of just ignores what happened and continues on with their day.
Question: If the polluted water supposedly killed Penguin, then how come it didn't kill Max Shreck considering that he ended up in the water because of Catwoman?
Question: When Selina/Catwoman has Schreck cornered, she says that him, the Penguin and Batman killed her leaving her with only six lives left. I understand that Schreck "killed" her by pushing her out a window and that the Penguin "killed" her when she fell through a greenhouse, but how could Batman have killed her? She landed safely in a truck filled with kitty litter after she got knocked off the roof, so that can't count.
Answer: In each of Selina's 3 falls, there was something that broke her fall enough to save her. In the film, she never died from any of the falls. Her line about having 6 lives left isn't literal. So while the kitty litter did save her, she still attributes the fall to a loss of life at the hands of Batman, because were is not for being lucky and landing in the truck, she might have actually died. Just like she was lucky enough to survive the fall at the hands of Schreck and Penguin but still blames them for a loss of life.
Answer: Having nine lives is all about luck. They refer that to cats who appear to have nine lines because they are able to survive high falls. But for a human it refers to having a lot of luck. She was lucky to land on the kitty litter whilst she should have died from the fall, therefore she lost a life.
Question: Did Batman mean to kill The Penguin?
Answer: Not intentionally, the rockets were aimed at the abandoned arctic zoo structure, not at the Penguin himself. He was caught in the crossfire.
Question: How did Penguin assemble his gang if he had never left the sewers?
Answer: He's left the sewers before. In a scene where Bruce is reading through old articles, the film itself blatantly implies that at one point in his life, he was taken in by a traveling circus and advertised as the "aquatic bird boy", which is where he met most of his gang. He retreated back to the sewers after children went missing, and he was blamed. The implication being that he either kidnapped or killed children out of rage for having what he never had - a family.
Answer: He didn't bite it off, but almost. The people in the room are all just power and money hungry, they decide to ignore it in hopes to keep their job.
