God formally disproven

[FallentoReason]

One of the properties of God is that he is omnibenevolent. This directly implies certain things about the world he would create. These are the implications:

1. God is omnibenevolent.

Therefore,

2. God must create the best world, otherwise he is not omnibenevolent.

Therefore,

3. The best world must be one where the creatures can freely choose to only do good actions.

Otherwise,

4. God is not omnibenevolent because it is impossible for God to not want to create the best world.

Therefore,

5. If God is necessarily omnibenevolent then evil cannot exist.

Conclusion:
- Evil exists meaning God is not omnibenevolent. Therefore God does not exist.

EDIT: I'm half asleep so maybe my reasoning has a few holes here and there. Feedback on how to improve my argument is more than welcome. Also, feedback on why I'm completely wrong is more than welcome.
