I was once a Christian and thank God I've become a Muslim, at least knowing some intricacies that Christianity cannot truly explain.
In Islam, Satan was created from smokeless fire, therefore, he is a jinn. The fact is, there were some jinns who accepted Islam. Thus, in this context, they are like human, some are evil and some are not.
In my opinion, God purposely made evil in this world so mankind may decipher what is good from evil. He should know how to avoid evil from all the warnings He gave to mankind; from the revelations given to His prophets. Through evil, man would constantly ask Him for protection and God is All-Knowing, the Most Merciful.
God loves man who committed evit yet ask Him for forgiveness. I read in Qur'an or may be Hadith, that says if man is soo good and does not commit mistakes, He may change mankind into some other beings, meaning the love of God is greater when man commits a sin and ask for His forgiveness and guidance.
Angels were created from light and their mindset is just to follow what God wants them to do, they cannot refuse, they don't have the ability to do so unlike man or jinn who were given the option to think otherwise. Therefore, it is wrong to say Lucifer or Satan is a fallen angel, he's not! He's a Jinn.
Jinn and mankind were created with the option to follow what they think is good for them, evil or not. But man, unlike Jinn has the ability to repent from his sins. And this is the most dearest gift God has given mankind, repentance from his mistakes.
Why does God love mankind more than angels and jinn? It's because we repent and ask for His forgiveness no matter how grave it is! And what is it that man possess why he was created in the first place? When Adam first opened his eyes, God asked the angels and jinn to prostrate towards this new creation, but Iblees (arabic word for Satan) being arrogant didn't do so, hence God made him an outcast.
Iblees said: “O my Lord! Give me then respite till the Day they (the dead) will be resurrected.” Allah said:
“Then, verily, you are of those reprieved, “Till the Day of the time appointed” (Quran, Surah al-Hijr: 36 – 38).
Adam was commanded by God to name that which he sees around him. So Adam gave names to all His creations, trees, mountains, animals, etc. The angels and jinn were aghast how this new creation new something they didn't know. That's how we are today, naming every particles we see or cannot see, even the microscopic bacteria we have a name for it, every single part of our body we have a name for it, every single plant and animal in the planet we have a name for it, the streets we go through we have names for them, and so on.
Hope I have given you a good perspective why we should always depend and ask our Creator for guidance and protection from the outcast Satan.
And Allah knows best.
