You might want to take Furion aside and educate him as to what Christianity actually teaches, BobYes - no savior = no cleansing of SIN = rejection at God's final Judgement.
YES - temporarily, and then The Lake of fire for eternity.
What you left off, naturally, is the infinitly more favorable experience of those who DO (under conviction of sin) REPENT of their sin, surrender to God calling upon Him in FAITH (that He gives) for salvation by the SIN OFFERING of Jesus on the cross.
Atheism (which is generally nothing more than common agnosticism) offers nothing during physical life, and a terrible penalty when physical life is over.
He doesn't seem know...
As to it being "infinitely better" to give one's self to Christ, I don't see it that way at all
I think it's better to live a life of integrity and then, upon death, go to Hell / Lake of Fire than it is to betray one's integrity in return for a less painful afterlife
