Literally whatever it takes to save his friends.
Save them?
I think he actually wants to kill them AND all the humans too...
No, he wants to save his friends and the rest of Eldia. Unfortunately, Marley has spent the last 100 years convincing the rest of the world that all Eldians are evil devils who must be completely wiped out without exception, so the rest of the world is determine to kill all the Eldians. Eren had to choose between wiping out all Eldia's enemies (which is basically the rest of the world), or letting himself, his friends, and all the Eldians be killed. Would you willingly sacrifice yourself and all your loved one for people who have made it their life mission to making your life miserable, murdered your family, and trying to kill you and everyone else in your nation? Because those were literally the only two options Eren was left with, and he decided that he chose to save his people, and to do whatever it took to save them.
Well you are right!
But i think if he kill all the humans (except his friends) he won't stop and he will go full crazy mode and want to kill the rest of humanity!
what the hell happened?!
Is this the end?
Goodbye humanity!?Eren boy what the fuck are you doing?
