Attack on Titan: What Would Happen if Eren Never Kissed Historia?
Eren Wouldn't Be On A Rampage
The easiest thing to decipher from this hypothetical scenario is that Eren wouldn't be on his current rampage, mostly because he never would have had the power of the Founding Titan to begin with. Before diving into that scenario, which is a whole can of worms on its own, Eren would effectively be flying by the seat of his pants, not knowing what events were to come and thus not being able to push toward the future he sees as one that would create happy and safe lives for his friends. Without being given a window on all that was to come, Eren might still be that same character from the first three seasons, attempting to figure out the world while fighting against the advances of Marley.

This is where we get into the "nitty gritty" of what Eren not kissing Historia's hand would result in, aka the time travel aspect of the fourth season. Eren went back into the past with his brother Zeke to witness the events of their father's life. Unbeknownst to the Beast Titan, Eren was able to change the past and push Grisha to eliminate the Reiss Family and add the Founding Titan power to himself. If Eren hadn't learned the future, this time travel adventure never would have taken place and Grisha would have stopped himself from eating the Founding Titan and most likely dying as a result. Even if Grisha had survived, he most likely wouldn't have passed on the power of the Attack Titan to Eren, focusing more on the power of Ymir when it took place originally.

Even if Grisha hadn't gained the power of the Founding Titan, Bertholdt, Reiner, and Annie still would have brought down the walls in an effort to bring said powers back to Marley. The question would then arise as to whether the trio would actually be able to take on the Reiss family and gain the Founding Titan's ability for themselves, but that's a question for a different article. The events of the series might have continued the same way for the first half of the premiere season, though we can certainly think of one thing that would have happened differently...

If Eren had never inherited the power of the Attack Titan thanks to his own time-traveling escapades, then he would have been killed in the first season when he was eaten by the bearded Titan following him saving Armin's life on the rooftops during their first mission. Without having the power of a Titan on their side, the walls would have eventually completely fallen in the face of the rampaging behemoths, most likely meaning that the Eldians of Paradis would have been completely wiped out before the Scout Regiment was ever able to discover the truth of the world outside their borders.
prevnextOr Maybe Grisha Played A More Active Role
If Grisha survived the Reiss attack when he couldn't pull the trigger on chowing down on the family, perhaps he might have escaped with his life and helped the Scout Regiment with the intrusion of Reiner, Bertholdt, and Annie, creating a whole new string of events. There are many different possibilities for how the series could have continued, but rest assured, the finale of the series would have been far different from what we know today had Eren decided not to kiss Historia's hand and set off the events we now witness today.
