The demonic operates in a very deceptive manner regarding it’s general behavior and even so much as to what they actually are.
The Glorification of the demonic purpose and intent is to instill fear and doubt in our own interactions with them. They quite often appear as angels of light, giving good things to those who obey and submit to their rule.
However this in itself is based off the reality of the situation. Despite the mass belief that they are hideously deformed monsters. This is a partial truth. They are actually fallen races and individuals that fell for Satan’s first deception.
They have all the traits of a sentient being, not a mindless zombie, I’ll be it more evil then most would consider acceptable. However they can feel just as we can, and just as we do they rationalize away hurtful and dangerous behavior as if it were the end result that mattered and not the path.
