First of all, the fact that he is God gives him the right. Secondly, NOBODY is perfect, but nobody is put into eternal suffering for "not being perfect". That's not even what the bible says, so you're just wrong.
I think it's fair that he gives us the choice.
We won't remember the wicked when we are in heaven, nor do we want them in heaven. I think it's totally fair and appropriate for God to separate the wicked from the righteous. Do you think it's fair that people who are evil should be given the same reward as people who are good? What kind of God rewards evil with eternal paradise? I find that idea sick personally!
I've heard preachers talk about serial killers who accept jesus and are saved and go to heaven. I think killing os pretty evil (but your god and his followers in the old testament seemed to kill alot...). So if a serial killer can get into heaven, doesnt that defeat your arguement? Also, I dont care if he's god. If hes sick and sadistic and makes his creation suffer on earth and possibly in the afterlife, he doesn't deserve worship. Also the bible mwntions predestination and that some are destined for hell. Sounds sick to me. I'd rather worship Satan. I think he had it right when he defied god.
