As one that have been quite certain my toaster is evil - throwing toast into the sink over an absurd distance, I recommend treating your toaster well. Besides it is an electrical device you put stuff into with your bare hands.

Heh, in fact I don’t actually own a toaster. It was just an example.

But in general I treat my devices well; that doesn’t mean I need to think they are conscious beings, however.

But if it seems to be possessed by a toast hurling daemon? ;-)

In that case an exorcism may indeed be necessary.

Heat it to a crisp, oh wait.
