Should I start analyzing about the vampire mentality and the fact that human maturity cannot follow that logic? In that case Caroline’s vampire instincts and perspective are not mature enough but Camille’s human view point is? Ok sure.
Caroline is immature. Right. Because if she was a mature woman she would be able to survive abuse and compulsion rape (Damon), she would be able to earn her way, fight and prove to anyone that she can be a vampire, she would be able to show her mother that she is not a monster (through actions not words), she would be able to control her bloodlust like no other vampire, she would be able to help a new werewolf transition even though that could kill her, she would be able to live through multiple torture sessions, she would be able to stand and survive when her father would torture her and then she would forgive him and then would see him dying while she would constantly act with grace; she would be able to support her friends while putting her life on the line each and every time; she would be able to see good in Klaus when she knows that he is a psychotic sadistic mass murderer that has been torturing all the people she loved (including her), she would give Klaus a chance to gain her respect when he was going to sacrifice her and when he killed Elena, Jenna, Carol, thousand more and turned her boyfriend into a mindless slave and then exiled him. Caroline would be mature if she would still have humanity in her, if she would still care for emotionless Elena that tried to harm her mother and kill her, is she would still try to keep a much older vampire like Stefan in control. She would be a mature woman if she was one of those people that when hardships come along they try to keep their normalcy and go on with their lives, even laugh, have fun and doing silly things that make them smile and make others smile too.I
