That is not how Discovery decided to roll so far.Stories need conflict, but they do not need to have "bad guys." Look at the Trek corpus as an example. Sometimes the antagonist was a species (the Borg or the Dominion). Sometimes the antagonist was a particular villain (Q, Dukat, or Khan). Sometimes it was a force of nature (the many anomalies/negative space wedgies). In some of the most interesting episodes, the conflict doesn't come from an antagonist directly, but is internal to the characters themselves.
