I’ve asked this type of question to evangelists in the past:
What if you got “saved” by Jesus at age 51, then would you have gone to hell if you didn’t live that long? Like the “unsaved” college students who died so young? No, they didn’t go to hell, and they are actually alright right now.
God knows what love means, and says that type of afterlife doesn’t exist. Everyone will eventually be ok, as cruel torture goes against ethics. And even a decent judge will not put a convicted mass murderer in an endless torture chamber, so God will instead put him into the dungeon for 30 to maybe 79 years, and then he or she will go through a process before moving forward.
