Well, it’s page 2, so now I’ll explain the scenario and my own answer.
The death train question is an old philosophical question, which is meant to stimulate people to think in ways they hadn’t before and to see what morals people have. Essentially it is meant to be unanswerable question, because the person, not sure of what to say, keeps asking for clarifications on the scenario, until it becomes incomprehensible. However, this would only work if you have flimsy morals or if you aren’t that good at ethics. The real trick of the question, though, is that you can only use philosophy, no religious beliefs or morals; however, since moral theology falls under philosophy, you get a kind of loophole to the rule.
My answer to the death train question, I would take the right track. My reasoning is that the baby has no personal sins, so it wouldn’t go to Hell, and, if I pray for its salvation, it will go to Heaven. So there is no loss at all; the baby goes to Heaven and the passengers onboard don’t die.
There is a Christian equivalent to this question, too. It goes “Who would you save from death, Jesus or a baby?” The correct answer is, again, the baby, because Jesus must die for our sins, and, as He taught, whatsoever you do to the least of His brethern, you do unto Him.
