Harvesting Negative

[Ashim]

I would say to become negative you would need to do things that are STS in nature. Such as taking advantage of someone consciously for your own benefit.

Not consciously. The STS being often thinks it is positive and 'twists'  perception of deeds to fit that mould.
Hitler believed he was 'doing right'. All a matter of perspective.
At a certain level or vibration there is no right/wrong or good/evil simply polarity, or male/female.
One tends to act in a mode of self preservation even if the native polarity is not consciously known.
Thus negative may believe to be doing 'positive'.

I believe that Lucifer was indeed that one wanderer (of Ra) who entered negative time/space.
