**SPOILERS FOR SEASON 1 (and 2 i think kind of)** also spoileers for darling in the franxx. for like. the whole show.
So basically aot and ditf are very similar concepts, since klaxosaurs which they have been killing as the enemy the whole show, turn out to be humanoid klaxosaurs that turned into the weapons to protect themselves. the difference is this changes peoples minds in ditf, but not in aot, because by the time they find out, they have killed real people, so it's not like they'll start having remorse they didn't already have.
Idk.
