There is hope for everyone to get to Heaven, but by no means should we on Earth be making pronouncements on which specific people are in Hell. That's way above our paygrade and I'm happy to keep it that way. People like this just make all Christians look stupid.
There is a list of people I expect to be there. If the most heinous examples of total pieces of shit known to humanity are not in hell then the term is meaningless. Not that there is any evidence to support its existence.
Jesus told us not to judge others for the sins that we ourselves also commit. All the time we spend trying to decide the state of others' souls would be far better spent taking the logs out of our eyes before yelling at others about the specks in theirs. Other people's salvation isn't your problem, you can't force people to accept Jesus. (Especially after they have already died.) You can, and should, instead become a shining beacon of grace that attracts people to the faith.
Someone else mentioned whether or not Hitler is in hell. I really don't care if he is. It isn't my problem. Jesus saved a man who was right beside him in crucifixion moments before they died, but that doesn't mean I'm going to hang my entire faith on the salvation of a certain person.
If you're curious, you should read what some classical Christian writers have said about Hell. The best summary I can give is that it's a place of such unbridled, horrifying hatred that people will tear the flesh off their bodies and throw it at other people while burning alive because they hate each other so much.
Further confirming my theory that Hell is actually the real Heaven and you definitely don't want to go to the fake one by accident and suffer eternity with those people and that "God".
MLK was reincarnated on another planet to complete a new task.
Racists are reincarnated as a member of the people they were racist against.
Life's about growing, if you devolve into a racist, it has to be made up in another life, or go straight to hell for refusing to grow as a sentient.
Ironically if the Bible had specifically called out race-based bigotry as seen hundreds of years later during and after the African Slave Trade it would have been pretty good evidence of God's omniscience.
Or it would have caused some sort of time loop since Christian Europeans wouldn't have done it if it was explicitly called out.
