since the last chapter, Lucy is doubtful of that Eclipse door and she knows that it's a mistake to open it. I know she is sane and not possessed as everyone thinks. and Future Rogue tries to stop her from closing the door because in the future, Rogue is Evil and very obsessed with his power just like Acnologia a long time ago when he was still human. If Lucy in the present closes the door, the future Rogue will not exist like Future Lucy because chaos was prevented and the dragons coming is postponed. I think in the future, Rogue becomes obsessed and kills the dragons like Acnologia and plans to overthrow him as the new Dragon King. In the present, Rogue is a kind person who wants to care for his friends. And by not opening the gate, Present Lucy saves not only her future self but the future Evil Rogue as well.
