Yes, it can be written as villagers are  normally simple people.
It would change the meaning as 'the villagers refers to villagers from a particular village and just villagers refers to people from all villages

yes , if we write without 'the' , it would change the meaning of the sentence.
the villagers are normally simple people means that the people of a particular village are simple.
villagers are normally simple people means that all the villagers of this world are usually simple people.
