Ok, from what I can tell the whole problem with [evil] can be shown in one spell:
Deathwatch
On the surface, for a good cleric, this looks like a great spell. Let's you know who is hurt and how bad, basically come up with a strategy on how to keep people alive.
I can see that. Looks good on the outside. But what is the spell actually doing? Let's not just look at the ends and say "Oh that spell is good because it tells me who to heal" but rather look at the entirety of the spell, it's full function, purpose and result.
"Using the foul sight granted by the powers of unlife" - ok...that sounds pretty darn evil. What foul powers of unlife would grant this ability to those who would use it to preserve life? Instead I would think that they would grant it to those who most want to deal death....evil people....So in this case perhaps it is not the deity blocking the good cleric from using the spell, but rather the evil powers not granting it.
The spell then goes on to describe the different levels of near death. Pretty mundane there. But the last line says that it grants the ability to see through feign death. What person in need of healing would fake being dead? Instead, this would allow an evil person to tell that someone was a faker and needed to get put over. That is the function of the last part.
After reading the spell and thinking about it, this spell is DEFINITELY a good candidate for the evil descriptor, and while does not directly do anything evil, it sure as hell is not on the good side of the fence.
