There’s no such thing as evil.
It therefore has no fundamental traits.
You’d be hard pressed to find anyone who thinks of himself as evil. Everyone is the hero of his own story.
Take “the dread pirate roberts” you know it’s a reference to The Princess Bride right? The hero of The Princess Bride?
Now Ross ram a high drug site on the dark web.
Was Ross evil? He certainly didn’t think so. He philosophically disagreed with drug laws. The Silk Road didn’t trade in things Ross thought were evil (I seem to recall from the write up in wires that he banned human trafficking etc). He simply thought everyone should have the right to choose for themselves. I bet he thought he was providing a service.
Was he evil? Not in his own mind. Did he seek fame with his name? Err, no? He was choosing a handle to specifically mask his name (he always planned to play the “it was the other dread pirate roberts the whole time” card)
I don’t think you can point to a single person who thinks of themselves as evil. (Even psychopaths don’t think of themselves as evil, they just don’t think other people are worthy of consideration. —I seem to recall that hitler was a vegetarian. If you asked him he’d say he was a hero of his people.)
And as for criminals seeking fame… probably no more or less than any human seeks fame. Or maybe to say it another way, everyone probably seeks recognition of skill.
