Yep. Pretty much it's your fault. But if you had not heard of God, it might not be your fault except a little.
The prodigal son returned to his father. Did you return to God?
The joy of the prodigal is in his father's home. Are you calling from Heaven?
Yes, it would be a shame for an agnostic, etc. That's why we all need to remain alert... so that we can show them the error of their ways.
What does it matter to me if you jokers believe in God and are saved or not? I mean, Jesus saved me, and because He asks, I express. But why would I personally care about you? Oh, sure, love. But here's my selfish reason. Eternity is a long, long time. And I need all of you that I can get to be there with us just to keep us from becoming bored (of course, that's the negative way to look at it; but we are still on Earth where negative things exist.).

You are worried about being bored in Heaven?

Furthermore, bad things happen to good people. There are lots of Christian martyrs that met horrible deaths. Also, I am sure there are many devout Christians in the world today that are simply having to go without toilet paper. Furthermore, I am sure there are quite a few devout Christians who have succumbed to Covid-19, and even though they were devout for 80+ years, they still had to endure a good deal of suffering before getting to rest in peace.
I advise that you stop blaming people for experiencing hardship for circumstances beyond their control and insinuating that somehow your God is punishing them. Life is hard, and most of us suffer to some extent. This includes, your savior, Jesus.
