Are there evil acts which are not sins? The answers to the question on the essence of sin seem to form a consensus that sins are acts of disobedience against things God specifically told us not to do.

Since sin is defined as disobedience and not related to evil, are there evil acts which are not sins?

(Sins which are not acts of evil might also be considered with the special exception of course for the disobedience itself being the only evil)
Since sin is in essence any act of disobedience towards God or disbelief and we know that God is good1 we can conclude that there are no evil acts which are not sins.

1In fact good and evil are defined by and measured against His nature.
