Young adults book

Young adult books that are dark, depressing, or include violence shouldn't be in our middle school libraries if it doesn't have a change in the end or has no hopes in the main characters goal or life because they are basically just too harsh and and can make a teen change. If a book does not have a change especially if it includes violence or dark actions in the book teens shouldn't be reading it because then they wouldn't be getting a "ah-huh" moment. The young adult books that don't have hope are just so depressing and when kids get depressed some start cutting or hurting themselves for sure I know teens do not look cute cutting also no parent would want that.
     Young adult books that are dark, depressing or include violence shouldn't be in middle school libraries If they don't have a change in the main character or have no hope in the books. The reason I make this statement is because if the book doesn't have a change it has no point . For example in the passage "The 'sick'-'lit' books aimed at children" it states "she added: I'd finish reading and immediately reach for my blade" if the book jess (the girl who said the quote) read had a change in the character why would jess cut herself teens just don't cut them selves just to be cool everyone always has a reasons and jess reason was because "the book put into words what she felt" this young adult book is causing a teen to do harm to them self is that really what parents want there 13 or 14 year old reading harmful books that can make there kids turn into cutting maniacs.Another example is because y.a books are too depressing when theres no hope in a character the book starts to get gloomy and then the reader start go "hey I feel that way too now" For example the book "after I die" was based on a 16 year old girl who had cancer and was writing a list of what to do before she died in the text it states "tessa complies a list of what to do before she expires" so that tells me Alright so my character is down (feeling low) because she has cancer but wouldn't she be determined instead of having no hope that she will live. This book is too depressing for teens but the worst of it is that "they're also aimed at children as young as 12" I mean that's still a preteen still coming out to the world little by little they shouldn't be reading these books that drag u down to darkness.
     Other people who disagree with taking down .Dark, depressing or include violence y.a books that shouldn't be on the libraries might think it bad to rate book but I mean is it really bad?. If rating book were bad there would be books of sexual, raping, and murder on the libraries because rating a book means seeing if the book is too dark or not. Yes, some y.a books give lessons and people change but the author of those y.a books don't really stand out that change which makes the reader/teen harm themselves. If y.a book weren't judge then teens wouldn't be teens they would be "monsters".
     In conclusion y.a books that are dark depressing or include violence shouldn't be in middle school libraries if it doesn't have a change in the character or if the character has no hope. When reading a book teens relate there life with books and they keep on reading till the end just to see how the main character will end and to relate how they will end there problems.
