I don’t understand where that pedantry comes from, with all due respect.
The modern English word “evil” comes from Anglo-Saxon “yfel”, which itself means “bad” in our modern sense; as do other such derived words as German “übel”.
Now the word “bad” is presumed to be derived from Anglo-Saxon “baeddel”, which actually means “hermaphrodite”. Perhaps this word is a misnomer?
I said I don't insist. Etymologies are nice, I love them, but not enough to study them formally. They don't tell us current usage or meaning. Bad is a more manageable concept when compared with the concept of evil and the use of the term "Bad" helps one to more refined discriminations as it is pointing to the fact that the individual has deficiencies. For example Hillary is a liar a person who lacks the ability to tell the truth. Hillary is greedy for free money thus lacks temperance.(She has many other vices) Satan is evil and thus an entirely different order of being not really manageable by Human beings. Once again I do not insist upon my interpretation/p>
