>>4... Keep in mind that canonically speaking, God made humans to worship him. God condemns those who do not worship him to a hell of eternal pain and suffering.
If you follow the bible, then he's not exactly the kindest role model here - If you don't worship and serve, he doesn't really seem to give a damn about you. God "flooded" the world because the majority of them weren't adequately kissing ass. He destroyed entire cities because a few people inside were being obstinate about not worshipping.
Ah, don't forget Sodom and Gomora - Those were destroyed without remorse or a second thought because they "strayed" from his worship. That is to say, they were exercising their free will.
Hell, there was an entire
massive religious era which revolved around this. You might be more familiar with the "fire and brimstone" concept of preaching? The years upon years where the church pretty adamantly instilled "fear and obey god" into it's members?
The concept that heaven would lack free will seems to logically go hand in hand with the rest of the stuff. God doesn't especially seem to care about free will in the first place.
It's kind of a catch 22 - You have free will to do whatever you want. As long it's what God has decided is okay for you to do.
