The Catholic Dictionary defines Evil as:
A condition resulting from some imperfection
If you mean by “Evil” that something is Bad then logically speaking; if something is “Bad”, that is a description of a good thing that is not doing what it’s supposed to do. i.e. a banana that has gone “bad” means that it is inedible, and therefore does not fulfil it’s purpose; or a young boy who is disobedient to his parents is refered to as having “bad” behaviour. An angel that was created to Worship God, but chooses not to would also be defined as “bad”. All of these examples, and any others that I can think of, presumes that
all things were created good.
