The fucked up with the whole CYCLOPS IS HITLER GUYSE thing is that after MARVEL "rebooted" things with Secret Wars they decided to take a page from DC's book and do a time-skip. So every book already started with the idea that Cyclops did something really, REALLY bad that fucked everyone over and pushed relations between the emerging Inhumans and the mutants back. So everyone from the Inhumans, the X-Men, the Avengers, and so on called Cyclops the new Red Skull.
But here's the kick: the writers had no fucking idea what exactly Cyclops did in the past or where exactly they were going with this story. It was a move done out of pure pettiness for Marvel readers finding Cyclops cool and just back before Secret Wars rolled out.
So eventually they decided to settle the conflict on the whole Terrigen clouds thing and write their way from there, but again they fucked completely with the execution because in the end... what Cyclop ended up in the prequel minis wasn't that bad at all? So yeah. Marvel fucked it up.
Honestly, i'm baffled by the whole Cyclops situation. I've never seen a publisher so intent on killing a character popularity before and being so, so fucking comically bad at it.
