It is not possible to have complete neutrality because everything one does regarding choices between good or evil is either good or evil.
If someone is G-d forbid, being robbed or drowning, for example,
someone watching can either try and save them or at least try and find someone who can save them wghcih would be doing good.
Sitting there and watching would not be neutral, it would be aiding evil by not doing anything (or even trying) to stop it.
If the person had absolutely no way to get hep and couldn’t do it themselves, that would make them putt’ter, “”””not”””” “neutral”.
Putt’ter just means someone is excused from doing what really they should have done, not that it was ‘OK’ to not help, which would have been neutral.
What if they were OOnis? That would just be a higher level of being excused, a “better” excuse, as it were.
