Here's my theory: at some point on history a relatively small portion of humanity gained the power to create titans and decided to use it to create an alternative society where they were the leaders. I'm obviously talking about the First King, The Reiss Family and the other noble families (The Asians, The Ackerman Family, etc). The used mind control to lure more humans to there lands and then used the titans to create the walls and to eliminate the rest of humanity. This happened about a hundred years before the main story starts. So, apparently the rest of humanity (the people outside the walls) are the real "good guys". They want "the total annihilation of everyone inside the walls", as said by Bertholdt, because since the beginning the Reiss Family had been using the titans to attack them. All they are really doing is defending themselves. Also, we now know that they are a far more advanced society than the people inside the walls but even so until they gained the power to create intelligent titans (Annie, Reiner, Zeke, etc) the didn't attempt to attack the walls. This was probably because, even with their tecnology, they were not capable of killing the titans. Let's not forget either of the day Bertholdt destroy Wall Maria: that day Grisha killed almost the entire Reiss Family, coincidence? I think NOT!!!!! Since we know Grisha is an outsider we can conclude this was probably a cordinated attack. The original plan was to kill the Reiss Family entirely and to achieve this they used the breach of Wall Maria and the Collosal Titan as a diversion so Grisha could get to Wall Sina (Where the Reiss Family lived). After the Reiss were all dead, humanity wouldn't be submmited to mind control anymore so the outsiders would use this oportunity to integrate them (the people inside the walls) to the "real" world. Obviously this didn't happened, but why? Because that day Carla Jäger died. Grisha had fallen in love genuinelly with Carla and when he heard she died he changed his plans. Now he wanted revenge on his own comrades but he couldn't live with himself for he was indirectly responsible of his wife's death. So he gave Eren the titan serum and let himself get eaten in order to transmit his powers to his son and also to punish himself for Carla's death. In Grisha's plan Eren is supposed to use his powers to "avenge his mother", as said by him. Obviously, Grisha didn't wanted the extermination of his own people until the very day he died so the books found in his basement will reflect the exact opposite idea: that the people outside the walls are "good" and the people inside are "bad". However, now that every Reiss (except Historia) is dead the only thing left to do is for both sides to talk it out an have Eren get rid of all the titans. This is just a theory ;)
