Can the "Devil" be seen as virtous?

As I talked about in my last post I find it hard to make out why "God" who can make these virtues cant follow them, what if the devil can show signs of virtue when "God" can be seen as sinful.
after watching the documentary about the history of him I found out some interesting facts about Satan:

• the snake in the garden of Eden wasn't the devil
• he wasn't a fallen angel it was a background story created by monks to keep people on the righteous path.
• His first appearance in the bible was him torturing a donkey but overall Satan hardly appeared in the old testament or the new testament. 
• Jew's see him as a minor angel in gods divine plan who is only doing his job and is not the face of evil.
• He is a prosecutor, part of god's employment.
• In the new testament he doesn't tempt Jesus into evil but asks him to question why he is there.

His appearance has changed to incorporate other mischievous or evil gods. such as "Pan" from Greek mythology which allowed the devil to inherit goat legs and horns.
 
The idea of making a character similar to him but other emphasising his temperance as a hard worker for "God"
But at the moment I will continue looking at other ideas and won't stay fixated.
