it was more than two lines, there was more than one of them ( we have been over this already there were DOZENS if not more ) we are talking a hive mind or collective consciousness, the sundering was deliberate.
We SAW her do it. Remember?
"So let there be no way back, from that temptation, I sunder us. No more shall Man have wings to bear him to Paradise, henceforth, he shall WALK
"
She did it deliberately, her reasons for doing so, clear.
She did not "deliberately kill anyone", she changed our path so that we did not follow the Ancients path and make their mistakes, we had to find a new way, to temper us, prepare us, alter our evolution and developement to face a peril she KNEW was headed our way.
Sooner or later, the Final Days would come, she wanted us ready and able to fight, to finish what the Ancients had started..to bring an end to a horrifying mistake one of their own had made. Hermes was a fool, reckless, besotted with his own beliefs and did not stop to THINK on what his creation was capable of. Even when confronted with his creations deadly potential, he never ceased to believe that he was right.
Mankind could not travel down the same road her peers had, their world was doomed to fail, Her children were the only ones who could hope to defeat the threat the Ancients had unleashed, thanks to their arrogance and smug superiority.
Hermes was insane, a fanatic, unable or unwilling to see firsthand the consequences of his presumption.
Whom the Gods would destroy..they first make mad.
