Q: How many Christians would be willing to be personally damned to hell forever if by so doing all other people in the world would get to go to heaven?
I can name one – Jesus! Jesus was the person who was willing to be damned to hell. It was an awesome work, one that I unashamedly say I could not do. We don’t do good works to get into heaven or to avoid hell; this would be futile. Jesus did for us what we could not do.
It also had to do with willingly being eternally damned for the sake of others (which also isn't the case with Christ, as the Bible teaches that he was resurrected and will return as King of Kings.)
Doesn't the Bible teach that some people will be better off in heaven than others? And don't you think that this influences the behavior of Christians?
People are influenced by their believed self-interest. This includes Christians. That's not shocking. It's human.
