Ok with Hell

It boggles my mind. How could anyone be ok with going to hell. My friend and I were talking with a young man. He was 21 years old. He started talking about the Bermuda Triangle. In Turkish it is called Satan's Triangle. I asked what he thought would happen if he flew over the Bermuda Triangle. He said he would probably die. So I asked him if he was sure where he would go after he died. He said no, but probably hell. He commented that he drank alcohol, had relations with girls outside of marriage, etc... all of which were sins. He didn't even blink. It didn't even seem to bother him. Which just flabbergasted me. I know that the Holy Spirit uses what we say and even what we don't say to plant seeds or convict hearts. Right now I'm wondering what we can do to get people like this begin to think about eternity seriously. There are so many people in this city who are following the god of materialism and they are ok with the fact that they are going to Hell.
