How can you kill zombies

You can't really kill the zombies but you can delete the person . Even if she/he is your friend , it'll be delete also .

You can only CURE zombies by making a cure elixir with an alchemy station or by purchasing a cure elixir at an alchemy store. When you have the elixir you must click on it and choose 'throw at sim' and an option box will appear with the sims you can choose to throw it at. Once the elixir has been thrown, the zombie will turn back into it's normal self, and the sim will most likely exit the location it appeared to be in.

You can also use the sunlight charm, but you must be a witch to do so. You have to build up enough magic skill until you are able to use the sunlight charm. You can build up your magic abilities by pressing on your sim and selecting 'play with magic'. The sim has to at least be as old as a teen to do so. When using the sunlight charm, click on the zombie you want to cure and and select cast charm and click on 'sunlight charm'.

If you want to delete the zombie click all keys at once: 'ctrl' 'shift' and 'c' and type this quote in the box: 'testingcheatsenabled true' or 'testingcheatsenabled on'. You then must shift click on the zombie and click 'object' and then 'delete'.

No because the zombies transform into human somehow
