First fact: It's possible to have a good Satan (adversary)
Second fact: Devil to mean false accuser is always in the negative sense.
Lets look at Devil
Even so
must their wives
be grave, not
slanderers (devil), sober, faithful in all things. 1 Tim 3:11
Here the translators could not use the word "devil" for very clear and obvious reasons!
Applying this approach looking at both words we find:
The meaning of "satan" (adversary) applies to various figures, including:
- God (2 Samuel 24:1; cf. 1 Chronicles 21:1)
- An obedient divine angel (Numbers 22:22)
- Hadad the Edomite (1 Kings 11:14)
- Peter (Matthew 16:23)
The term "devil" (accuser or slanderer) is used for:
- Judas (John 6:70)
- Women (1 Timothy 3:11; cf. Titus 2:3)
- Men (2 Timothy 3:3)
- "Sin in the flesh" (Hebrews 2:14; cf. Hebrews 9:26, Romans 5:21, 6:23), showing that "devil" can be synonymous with "sin," as further supported by Romans 7:17-18.
I could walk you through the true meaning behind every occurrence of these words, but ultimately, that won’t change the deeply held misconceptions you continue to cling to.
Your mind is closed on the matter, and as a result, you're not in a place to be taught.
