That line of thinking doesn’t bother you? Many have to suffer needlessly in hell but it’s ok it had to happen so some people can be happy in heaven?
Why are you surprised? Didn’t you know that the gates of hell are locked from the inside? That there is a very long line of people, banging on the locked doors, demanding admittance? They want to be burned in the eternal flames, they crave for the worms gnawing on their entrails… they choose to be tortured there for all eternity.

Hopefully there will be a nice documentary to show the details, so we can make a really informed decision to choose between heaven an hell.
In the meantime I suggest you read the book by the Rev John Furniss (what an appropriate name!) and titled: The Sight of Hell ( available here:
Fr. John Furniss - The Sight of Hell ). Especially the approbation, which says:
“I have carefully read over this Little Volume for Children and have found nothing whatsoever in it contrary to the doctrine of Holy Faith; but, on the contrary, a great deal to charm, instruct and edify our youthful classes, for whose benefit it has been written.” by William Meagher, Vicar General, Dublin, December 14, 1855.
