His inflation, although horrific from a therapeutic point of view, did provide the world with insights that went far beyond the mortal man. It was his fate and inflation may have been his meaning. We as Jungians, think about wholeness and balance. Can we however achieve a broad balance without exploring the extremes. A child is relatively balanced in their personality.
All functions are predominantly unconscious.
Who knows what the extremes might be for any function. But I do know that you can't develop a function by having its opposite conscious as well. My own experience in life has taught me that to develop something to an extreme will soon follow by a compensation to develop its opposite. Which must be developed to the same degree to achieve balance. If this applies to others, then a balance in the personality is no more than an arbitrary point which one is never really at for very long.
