Is it normal that i used to think adults and teenagers were villains?

When I was young I used to watch Codename: Kids Next Door ( which was a good CN show back in the good old glory days ) and I always thought the adults and teenagers were the main villains while growing up, even when looking at this now I think its quite funny that I used to think that. Another reason why I laughed at my old young thought because I thought it was kinda cute but also because I was developing but coincidently I also lived my adolescence and adulthood after those thoughts went ( it was like being decommissioned just like one of the episodes of KND). At the same time I questioned myself " What did I expect from 7 year old me? " considering that I was 7 years old when I had those old thoughts and those thoughts feel somewhat questionable. But hey since I mentioned that show I may as well watch some of the good old classics of Kids Next Door while at the same time questioning that aspect of my childhood.
