Dear Friend, I am glad that you did what you did in talking with him. Another person there really helps. I know this may sound harsh, but you can't be there all the time for him. You being there is great, but no human being can give him a purpose or a drive to live for more than temporarily at best. The other option is God. He even said that even more bluntly. Isaiah 57:21, "There is no peace, saith my God, to the wicked. " Who are the wicked? Everyone. Jeremiah 17:9, "The heart is deceitful above all things, and desperately wicked: who can know it? " Romans 3:23, "For all have sinned, and come short of the glory of God." glory means beauty, highness, perfection. Who is God? Isaiah 57:15a, "For thus saith the high and lofty One that inhabiteth eternity, whose name is Holy;..." Genesis 1:1, "In the beginning God created the heavens and the earth." (Holy means perfect and separate from all that is imperfection and wrong. Created means made from nothing. -eth in old English does the same as an -s)God even has a separate place to be for eternity for sinners. Revelations 21:8, "But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death." Revelation 20:10, "And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever." (whoremonger is a prostitute) So how can you, your friend, myself, or any one else for that matter, ever have peace? Romans 6:23, "For the wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord." A gift is free for us to receive it. Who is Jesus Christ? He is the same God I've been talking about. John 10:30, "I and my Father are one. " However, he came to earth for the purpose "that He by the grace of God should taste death for every man."(Hebrews 2:9) John 3:16, "For God so loved the world, that he gave his only begotten Son that whosoever believeth in him should not perish, but have everlasting life." So what do you do? Romans 10:9, "That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. " And after salvation, you have a purpose-serve him who saved you, and telling other people. 1 Peter 1:15-16 " But as he which hath called you is holy, so be ye holy in all manner of conversation; (16) Because it is written, Be ye holy; for I am holy."
I hope this helps.
