As per definitions that I have found on internet Shaitan is:
In the Koran an angel of high degree who was expelled from heaven because he refused to worship Adam at his Lord's command; often regarded as equivalent to Iblis.
Why is this considered bad in Islam (Ok, he went against God's command, but he must have had his reasons..)? How did we get from an angel that refused to worship to Adam to an entity/daemon that causes havoc and evil and that is feared by all humans and believers or various religions?
I understand that this was ordered by God, but to turn him from an angel to an Evil being is a little difficult to comprehend. Could someone shed light?
Actually I think he understood really how we humans are and that is why he made this choice.. (For reference I am not a Satanist, just a curious person)
