A criminal is like someone who breaks the rules of a big game called society. Just like when you play a game with friends and everyone agrees to follow certain rules, our society has rules called laws. These laws help people live together safely and happily. When someone breaks these rules on purpose, they become a criminal.
Think of it like a classroom where everyone is supposed to share crayons. If someone takes all the crayons and doesn’t share, they are not following the classroom rules. A criminal is like that person, but instead of crayons, they might take things that don’t belong to them or do things that hurt other people.
Imagine there’s a big book of rules that everyone agrees to follow to keep things fair and safe. When someone decides not to follow these rules, like taking something without asking or hurting others, they are being a criminal. It’s important to have these rules so everyone can feel safe and happy, just like in your games or classroom.
