Eyewitnesses wrote that Jesus raised Lazarus from the dead, and later rose from the dead himself. If this really happened it makes sense why none of the apostles were afraid to die for what they were certain was true.
So? The followers still all died. Whether or not they may have been happy about dying doesn't change that.
And I'm not sure what Lazarus has to do with this unless your suggesting that his raising means that he couldn't die i.e. he's still alive. That would be a very unusual interpretation.
It shows that this death is like a temporary sleep which God will wake us from. None who believe in Jesus will perish (experience the permanent second death after the judgment). John 5:28-29
