I am not on strong ground with the following, so I'll offer it as a perhaps.
The free will that is - er - glorified in many popular modes of Christianity is misunderstood and perhaps overrated. Christian teaching from the New Testament has a very strong piece that speaks of election and predestination, with which the libertarian minded West has great difficulties. Especially in democratically minded countries such as those of Anglo-Saxon heritage. Read the Revelation of John, the last 3 chapters sometime: while there is hope of glory for the saints, the doom awaiting cowards, the licentious, the rebellious, etc., is quite scary.
.....which I find interesting (and have for a while) that perhaps there is more reality to Ragnarok from the perspective of the gods who, in Christian teaching, would be denizens of the enemy; knowing themselves to be condemned, they do the best then can and are true to themselves out of a kind of self-respect/pride of heart. Just a notion.
