MVC pattern "requires" you to insert all your "business logic" in the Models. Models are used to access database and fetch data and mold it in a way that you just have to use a Controller to assign it into a View.

Needless to say perhaps, that you can bypass the use of models and write all your logic in the Controllers, but that would result in a very extensive and probably redundant amount of code. Controllers are used so you can call Models and Views, and exchange information from one to another with just a few lines of code.
