Is there a dark side of the force?

The Force has no "dark side" in my view but humans can choose to use their knowledge to destroy things, rather than build them.

Existence, itself, is free of any moral dimension, in of itself. For moral opinion is of man, and perhaps no other creature. And so ideas of right and wrong, good and bad, begins and ends with mankind.

Existence simply is, and those living pieces or consciousnesses that make it up, simply are.

The conclusions or interpretations we place on existence are simply our own projections, particularly those of a "moral" nature, and do not affect or relate to the true ISNESS of existence.

And ISNESS is one without a second.

There is no good and bad in oneness, just what IS.
