Let's go with k.i.s.s. either you're evil or you're not.
1.) Can you learn an evil spell list and not be evil?
2.) Can you cast spells from evil spellists and not be evil?
3.) Can you you worship a god of Char?n and not be evil?
4.) Can you be evil but not unlife?
1 - Yes
2 - Yes
3 - Yes
4 - Yes
If you were a Yinka (Y'Kin, tanara...) The list would be:
1 - Can you learn an evil spell list, and not be evil. Example - Water law. (Yugal is the god of fire)
2 - Remains the same as your original, but with different examples
3 - Can you worship a god of Orhan and not be evil?
4 - Same as yours. To the extent that people know of Unlife as anything else than another name for evil.
Belief in absolute Evil leads to absurd conclutions (Thats my philosophy at least)
Look at any group in todays society, or in history, that you consider to be evil. Do you think they believe they are evil? You can easily find examples of groups that were Evil (as declared by the church at the time) that nowdays are considered to have been Good or, at worst, a bit cooky. (Case in point the Cathar)
Belief in absolute good and evil mostly comes from religions, and the definitions all come from their holy texts. Well, that and AD&D where the gods of the gods decided what gods are good and what are evil.
