I was under the impression that some of the red choices/bad endings are mostly WIP and will be expanded on more once the main story is settled, at least that's what I interpreted from seeing some of the discussions about the game for a while now (and I feel like Hyao may have said something about the bad ends being WIP until the main story is done? dunno, maybe making this up).
And with Hissh, I was just theorising that there could be a separate variation of this storyline with the corrupted Othra/Roushk, since the character's goals seem to be lizard's mass corruption, which could be an opportunity for Hyao to come back to and write up a bunch of stuff for this ending.
Not completely sure what you mean by the Red/Green choices being different. At least in the most current versions, both the Logan and the Lizard corruption choices are marked Red/Green now, and show up the same in the quest log.
Also I would argue other Red choices still have pretty big effects on the story, especially the most recent one with the Seth/Lionel plot where the player can tell Everett about the situation. Afaik, choosing to tell locks you out of the rest of Seth's story and thus the new Western areas with the dwarves and goblins and the Yeti. The Logan choice is also pretty important, the recent swamp werewolf quest is different depending on the player's decision, and the Black Wolf quest seems to only trigger on the werewolf/romance Logan path?
Anyway, my point was that most players shouldn't really bother with the red choices in general right now beyond the immediate outcomes, since they will be effectively missing out on a bunch of content (side quests, romances, and, most importantly for an erotic game, sex scenes).
