People like salt but salt can be bad. The history of Abraham's nephew wife is a good example.
She was escaping the judgement of Sodom. She needed to focus on God to avoid the judgement.
But she was walking towards the Lord but she decided that the world's sins were more important.
There are many people that had a chance to follow the Lord. But these people will reject God and have the judgement of God in their lives.
The sins that seems good, these sins will guide a person to hell.
