God created evil

[useful idiot]

The only thing that is inherently sinful is deviation from the will of God. The free choice and human faculties given to Adam resulted in his decision to disobey God. God knew this obviously, as he is omniscient, but that doesn't make him culpable. Having created something tabula rasa, he is free from the creation of sin.

I assume what you're referring to when you said that God created Lucifer as perfect, you're referring to Ezekiel 28(a use of the king of Tyre as an allegory for Satan and probably for mankind in general). It says that he was blameless until unrighteousness was found in him. I can only assume to take this as Satan, and humanity, being perfect in creation because he(or they) had not yet rebelled against God. If sin is a lack of obedience to God, and goodness/blamelessness/perfection is the lack of pride and disobedience, then everything God created at its outset is good.

Unlike Satan, however, God has chosen to save those humans who will accept the sacrifice found in Christ's atonement.

Some hyper-Calvinists (who consider Calvin a heretic, funnily enough), will argue that God is the author of sin, but unfortunately like so many groups out there they've taken certain Bible passages and twisted them for their own ends, such as those that speak of God hardening certain people's hearts, and particularly and frustratingly 2 Cor 4: 3-4. This passage is a good argument for authentic "Calvinism", but when read the wrong way can lead you to ridiculous conclusions that are out of step with the rest of scripture.
