My theory is that the titans are continually used as a source of government control. One thing that brings all people to their knees and edge is fear. If the government leader can cause one common thing as a control factor of hatred and fear, they can keep society on somewhat of a leesh controlling them. Just like in the hunger games, the mass control was the use of the games to control the districts. The creation of the titans causes the whole population to be contained inside of the walls with their lives depending on them listening to the words of their leader. To the people inside the walls the leader is somewhat now their God and life giver. If they don't listen to what they have to do they could find themselves at the mercy of giant cannibolistic monsters (insert titan). I think it will be found out eventually and the corps will have to basically preform a governmental take down and re-create the whole system. I also believe during the creation process of the titans it's a pretty good guess they used humans in the main experimentation process. I think that just because of the shape shifters.
