What about people who never hear the Gospel of Jesus?
All people are "without excuse" (Romans 1:20) because God placed in everyone a conscience, and so all deserve separation from God (Hell). Also, there is no salvation except through Jesus Christ (Acts 4:12). It is just for God to condemn those who have never heard of Jesus for their sins. However, since God is loving, there's a possibility that people could hear the gospel after death (I Peter 4:6), and while we know some sins cannot be forgiven in the next age (Mat 12:32), maybe others can. Most likely rejecting God in life results in death, but those who never had a chance to accept or reject Jesus may be able to do so after death, as salvation is by faith through grace and not by works.
