How to Have a Declared Enemy in The Sims 4
Declaring an enemy starts with making sure that sims dislike you. This is easy, just do a bunch of mean or mischief interactions with that sim and they will no longer like you and your relationship bar will start turning red.

You need to keep doing this until you see a notification that tells you that your sim and your target sim despise each other. Once this appears you can click on the other sim and the declare enemy option should appear in the initial menu page.

After you click this you’ll get a notification that says that your sim and your target sim have had it and they are now enemies!

There are some funny things that happen when a sim is an enemy of your sim. For example, if that sim dies your sim can click on them as they are dying and you can choose sadistic glee and your sim will laugh.

Then, you’ll get a +3 Happy moodlet that lasts two days from them loving the fact that their sworn enemy has died.
Now that you know how to declare an enemy you can complete the public enemy aspiration or just go around being mean!
