In the book of Luke 18:9, Jesus told a parable about a man who went to the temple to pray. The pharisee stood by himself and prayed this prayer:"i thank you,God,that i am not a sinner, for i dont cheat, i dont sin, and i dont commit adultery, i fast twice a week, and i give you a tenth of my income as u cammanded". I tend to understand that the man was a good man because he does al dat d law ask him to do. But still yet the bible condemn the pharasee. So i dont knw, is hell really full of good people?

no

according to the Bible, Believing in Yahweh is the only way to heaven.
So yes, you may be the best person on earth but if you don't believe in Yahweh, You go to hell fire
