Gotta say outright, a god that punishes people for not believing in the correct interpretation of him... is a God who's heaven I wouldn't want to go to. Just do the math on regional factors alone. Fact is if you believe in a god, if you are born in a heavily muslim area, there's a 75% chance you'd believe in the muslim interpretation. If you are born in a christian area, there's a 75% chance you'll have the christian belief, same for hinduism, bhudism etc...

Fact is no matter how you slice it, if there is a correct version of god to believe in, at most maybe 1/3rd of people are in the right place to believe in that version of him. Meaning 2/3rds of the world is at a cultural disadvantage to not correctly beleive in the right version of god, and thus would be doomed to hell. That's before factoring in hundreds of other factors like life circumstance etc...

Simple fact is if a god exists, and is good, and has an afterlife (none of which are facts I believe in). I don't think belief or knowledge is any sign of fairness for such a being to do, and certainly sending things to hell for something that they are literally incapable of even trying to think about... is just nonsense for anything but the most malicious and evil interpretations of a god.
