It has been discussed at lenght here, too, still I can't understand how the creators don't get how bad of a look that is. I mean, most Catholics overwhelmingly do not believe gay/trans people are marked for hell,at all,even those "unchaste" (if monogamous of course). Apart from weirdos like the Society of Saint Pius X (now excommunicated by Pope Leo).
Hell should be full of obviously morally bad people like murderers,fraudsters,rapists,torturers and the likes (s.th Lucifer has implied). And sure, as I believe in purgatory, they absolutely could and should try to reach heaven (it's called hopeful universalism aka the hope that ultimately hell is empty due to God's limitless mercy. Not a heresy btw).
