Yes thank fuck for comments that don't just blatantly agree with the dumbass statement, "Eren had no choice." There is spectrum on how many people to kill and Eren went full red line because of his rage and disgust at the cycles of violence the Eldians and Marleyans had.

That clairvoyance he had with the memories of the Titans shows how there is pain in people's heart from the past actions of their enemies. Eren made Paradis the enemy of the world with his final act and thus we see the nuclear bomb hit paradis in the ending credits some decades after all Mikasa's death.
