Pride came for Lucifers own will.
If it didn't then you have God the author of sin, is that what you are saying?
Thou wast perfect iin thy ways from the day that thou wast created, till iniquity was found in thee. Thine heart was lifted up because of thy beauty,thou hast corrupted thy wisdom by reason of thy brightness...(Ezek.28:15,17)
There is a Cherub of God who rejected God from his own will.
That is the power that God gave His own rational creatures, the ability to say 'no' as well as 'yes'.
God always knew what Lucifer would do with his free will.
