It’s like religion. If you accept that God and Hell are real, then becoming a fundamentalist Christian and trying as hard as you can to convert as many people as possible is the only ethical option.
“God and Hell are real” doesn’t imply that whoever is not a Christian will go to hell. Even some Christians (e.g. present-day mainstream Catholics) acknowledge that.
I wonder what your last sentence implies, as I have found “present-day mainstream Catholics” to be more reasonable than many other denominations. Though it depends who you place in that group.

Presumably the Pope is not a mainstream Catholic.
“Even” as in “not only detractors of Christianity, but also some Christians themselves”. Edited to make that clearer.
