The "evolution" of Evil (in the consideration of UFO/UAP non-humans)

How can a non-human species commit evil deeds?

 
Humankind, we/us, live on a planet that began with a predilection toward destructive behavior.
 
Where, in the long route of evolution, did this tendency occur?
 
Some religionists would attribute human evil to “original sin” but that doesn’t explain much; original sin has not been codified exactly.
 
But with all the philosophizing over the years, beginning mainly with the early Greek savants, ethical and/or moral behavior has been defined in any number of ways, each harking back to some flaw in mankind’s mental evolution or, perhaps, a defective gene.
 
The ethical/moral behavior, or lack of same, is unique to this planet’s species – all of them, flora and fauna, sea creatures. Microscopic, all living things, sentient and semi-sentient.
 
So how could a non-human species have a semblance of evil traits and behaviors, unless they were formed on Earth, not extraterrestrial, not inter-dimensional, but formed on Earth.
 
The circumstantial “behaviors” of UFO interlopers, experienced or witnessed derive from an evolutionary path unique to planet Earth.
 
The results of that extreme glitch in specie evolution can’t be exported to other places in our galaxy or Universe.
 
And that “glitch” has to be corrected on this planet. Will it b e corrected by AI or will AI exacerbate the “glitch”?
 
Who knows or can tell?
