Well, it's more so everyone has a mistake or problem or two to them that they need to work on, rather than being one. Being one on the inside implies that you're purposefully trying to do bad, while making mistakes, having a problem etc. is just due to imperfections. We're all not perfect creatures, but you know, we can try to be at our best or try to work on thing, try to be better. Aaand then the people who don't try, or actually want some form of chaos, or like being mean are those type of people.
Just an explanation on what the difference is on being one on the inside means, and having mistakes or imperfections. So in truth it's more like everyone makes mistakes that can be worked on or fixed!
Edit: Hope that helps King-Pen! Sorry to add another post that derails the topic everyone, but the conversation was here and all.
