What evil acts are you suggesting specifically? It appears obvious that Jude is addressing a specific sin here. Verses 8-10 read:
"Nevertheless, these dreamers likewise also defile flesh, repudiate Lordship, and defame those clothed in glory. But the archangel Michael, when arguing with the Devil in legally disputing over the body of Moses, dared not bring a character defamation against him in accusation, but [simply] said, "The Lord rebuke you." But these men know not what they defame, yet like unsuspecting beasts, what things they observe in the natural, through these they succumb to bodily corruption. (Jude 1:8-10)
The sin described here is specific: Verbal defamation and evil speaking. It is a sin he is specifically focused on in the letter, and returns to it again in Jude 1:14-16.
I'd like to respond to this post, but the lack of punctuation and articles in certain places makes it very difficult to read. If you can, please reword it.
