Another hypothetical for theists.

[Amarok]

I think you misunderstand me.

Nope we understand your derp 

My point is that the Problem of Evil, from the skeptics side, is not a logical argument;

Yes it is because if a good god their is no reason evil should .

but rather, an emotional one based on incredulity.

Nope but nice try 

That you believe the world could be better has nothing to do with whether or not it actually could be.

Actually it does because it means said world is conceivable and possibly and for a creator god doable 

Secondly the state of the world most likely could be dramatically improved if everyone, including myself, always behaved like the best person they could be.

Or it could be if a supposedly perfect being made us perfect . Shifting the blame to humans to get your god off the hook will not work. 

That we choose not to do so isn't God's fault 

Yes it is the buck stops with your god. Appealing to freewill won't help you.

and doesn't negate that idea that it all started out pretty good until people started messing with each other

Yup and it's all your gods fault it went to shit blaming humans and appealing to free will is not going to help you. The buck stops with the creator .
