Despite the common belief, evil is NOT one side of a polarity.
Polarities are a result of applied forces. Wherever there is force, the result is what we call physicality. Different planes of existence are just different levels of physicality differing in frequency.
Wherever there is existence, there can be evil, because evil is an idea, not a place.
This simple truth tells us that both good and evil are the result of free will choices. It doesn't matter where you are.
For people who define Good and Evil as Polar-Opposites, POLAR-Opposites, such claims are ultimately a logical-contradiction; and what makes you believe that there is a «physicality» within each and every «plane» of existence ? What is and where is your evidence for such a claim ?
Anywhere there is existence, there is always a frequency in some form or another, whether be it a light-frequency, sound-frequency, radio-wave frequency, micro-wave frequency, psychic-thought frequency, ALL of existence revolves around FREQUENCIES.
And «thoughts» have to come from *somewhere* as they are NOT just merely «brain-generated» phenomena; not all of your thoughts are necessarily your own.
The simple truth tells us that perceived good and perceived evil stem from ideology and are also just perceptions based on one's thought-frequencies. It is one's ACTIONS (and expressions upon others) that matter. ACTIONS speak louder than words and determine whether where you are will be a «place» that contains so-called good or so-called evil depending on ACTION(s).
"what makes you believe that there is a «physicality» within each and every «plane» of existence ?"
Physicality means being able to sense it. Being on a certain plane of existence without being able to sense it is the definition of unconsciousness. You need to be part of the physicality of that plane to be there.
"What is and where is your evidence for such a claim ?"
No evidence needed, because the definition of the term physicality provides logical proof, as explained above.
"ALL of existence revolves around FREQUENCIES."
And all frequencies are physical, because they are a form that can be sensed.
"The simple truth tells us that perceived good and perceived evil stem from ideology and are also just perceptions based on one's thought-frequencies."
I don't speak of perceived evil.
"It is one's ACTIONS (and expressions upon others) that matter."
Evil is an action resulting from a free will choice. You can act in an evil way wherever you are.
Anything deemed to be in the category of what is called «psychic» phenomena or also «spiritual» phenomena or even «quantum» mechanics (also still referred to as quantum-physics via some sources even though it is a misnomer for the definition I am about to reveal) necessarily by definition is automatically defined and described as «non-physical» phenomena.
The history of «materialism» and its philosophy is also often called or perhaps even most-accurately called physicalism; and, for anybody who has ever come across a materialist, attempting to claim that there is any sort of validity to any form of psychic or para-normal phenomena, has definitely typically experienced the extreme-hostility that such materialists have against all things that they consider to have ANY connection to «spiritualism» (frequently because of past bad-experiences with religious-people who were extremely abusive towards them during their childhoods).
See also https://www.reddit.com/r/askphilosophy/comments/4runnb/whats_the_difference_between_materialism/ regarding what people often mean by materialism or physicalism and how things like «ghosts or spirits» are deemed by the physicalist-materialist to be non-physical and purely imagination-fantasy that does not exist in any physical-reality. Then of course there are plenty of people on the https://discord.gg/dB8JNrbQ (Politics & Religion) Discord-Server who are more-than-willing to «debate» some particular point or another (but only if you have far too much free-time on your hands; I am of the opinion that the vast majority of its «regulars» are far too dogmatic to be convinced or even to come up with a truly convincing & logical-presentation where there are no logical-holes).
Pure evil does exist. Here is a remote viewing of it:
