In the next place we must consider how angels became evil: first of all with regard to the evil of fault; and secondly, as to the evil of punishment.
Under the first heading there are nine points for consideration:
A Can there be evil of fault in the angels?
A What kind of sins can be in them?
A What did the angel seek in sinning?
A Supposing that some became evil by a sin of their own choosing, are any of them naturally evil?
A Supposing that it is not so, could any one of them become evil in the first instant of his creation by an act of his own will?
A Supposing that he did not, was there any interval between his creation and fall?
A Was the highest of them who fell, absolutely the highest among the angels?
A Was the sin of the foremost angel the cause of the others sinning?
A Did as many sin as remained steadfast?
