This is my `users_controller` method. it should be redirected if user is not activated. 

```
def show
  @user = User.find(params[:id])
  redirect_to root_url and return unless @user.activated?
end

```

Here I dont understand the need of return in the method as it would happen automatically before the redirect\_to is executed. I have seen many example but most of them have more if statements, so return skips those checks. Here, is it necessary?
