Any spells have the potential to do so, not just [Evil] spells. As I stated before: if a spell, by its inherent nature, was a cruel act (such as the Flensing spell)... such a spell would be an evil act. But if an [Evil] spell did not inherently match any of the definitions mentioned in the alignment section of the RAW (such as Deathwatch, Protection from Good, etc), it is only evil when used in an evil way (again, as defined by the RAW).
People are just stuck on the word, and not seeing its context and use.
