Does god take away free will?

we have free will, but god already knows what we will do, so he knows our future. he knows what we will do., given that, why can't he send us to heaven or heck based on this, since he knows who is saved and who is not? and speaking of heck, heck is used by many as a reason to believe in Jesus, in theory, heck is so bad it scares most into beleiving. this implies that Christianity is not an excercize of humility, rather the opposite. yes, greed, one of the seven deadly sins. also, god reads minds and can see at your attempt to deceive him. in conclusion, hw will send you to heck wether you pray or not. so in conclusion, most will go to hell, no matter how "godly" they are. so all those people who converted may really be going to heck. so confessing your "sins" is useless, as he will see through your deception.try answering this!
