Perhaps it is because we are evil by nature and deserve everything that happens to us?

Yes! Remember: "world hunger, slavery, human suffering, and the ills of the world" would be gone. My free will would be gone and I'd be happy. Everyone would be happy.

I'm about to play the devil's advocate here hehehehehe:

Without free will you'd have no way of knowing if those criteria were actually met. You'd be happy out of ignorant bliss, much like a man who lives as a hermit in a hut on the moon his entire life has no knowledge of any of the world's evils - but at the same time, has no knowledge of the world's good. This is the paradox of being self aware and holding the knowledge of the world's evils and goods - a dichotomy which Genesis speaks of. Adam and Eve lived in blissful ignorance until they ate from the tree of knowledge. They had no knowledge of the suffering of the world and thus these evils did not exist - until they made a conscious effort to be knowledgeable of them. God would rather have them live in ignorance and so he forbade the act of eating the fruit, and subsequently threw them out of Eden.

Was it not the way of the Medieval Roman Catholic Church which so heavily restrained any scientific advancement and pushed their own viewpoints on the matter? I'd say they were the epitome of free will violation. 

Once again, I'm just playing the devil's advocate and providing an interpretation of the arguments made. The viewpoints shared may or may not be what I personally believe. Don't hate me

But there are no more evils in the world. Recall I gave up my free will for there to be no evils.

Also, I gave up my free will, I didn't get IQ points knocked off. I can now only do good and no evil since, again, there is no more evil.

How? I gave up my free will for evil things to disappear. The stuff you listed isn't evil, that wouldn't disappear.

But things are still very much possible, it just wouldn't be due to free will. If I gave up my free will, I'd become a robot but a robot can still very much do things and because evil has been banished, I'd only be able to do good things. What those good things are wouldn't be up to me but they'd still be there.

Robots was the wrong word, I'd be a robot with human emotions.

if there is a god and everything we know spawned from it... then of course evil is also its creation

the strange thing is that to me this is self-evident to the concept of a god and yet religious people avoid this point like the plague

but the thing is... what is evil?

evil is merely that which is considered negative from the perspective of a particular group of humans and as issues like abortion show its in constant flux

if i kill 200 people tomorrow, sure to other people i'd be a pretty evil person

but, outside of human society will it matter? will it matter to fish, to dogs, to birds etc? no because its merely an abstract human concept

suppose the people were "terrorists"? suppose they were nazis? then it would be justified but from the pov of the "terrorist" its evil

the type of god i believe in is not a personal god that amusingly has all the trappings of human morality yet is omnipotent... which imo is the silliest thing ever

i'd think that a god would be beyond concepts like these because even in my own experiences i'm beginning to understand that words like "evil" and "good" really have little meaning because theycan be rationalised one way or another constantly
