The story in this game is a collaborative effort and the EN team decided to characterize EN Midgardsormr in this way, making him more mysterious, terse, and ambiguously adversarial than his JP characterization. You are free to dislike that authorial choice, but it's no less "correct" than the Japanese version because all people involved are full-fledged "authors" of the work.
