I don't get why people crave Revenge Endings in games with characters like Leto and Noah... They're so fucking naive and oblivious about their surroundings that it makes me not feel any sympathy for them at all.
I mean, how many times did they hear moans or weird noises around them and didn't react? In the case of Leto, in various scenes Rose had to take the initiative for a kiss or even for a fucking hug with Leto... In both HC2 and HC3, the girls clearly shown interest on being more intimate with the MCs, and they still acted like potato sacks...
The only point of Revenge Endings is to see very evil characters, like Zeno, getting what they fucking deserve. *insert Joker meme here*. But not really to see those MCs "getting some pussy". They don't really deserve it, lol.
But that said... Revenge Endings sometimes may still make more sense than Good Endings. Because, like other people already mentioned, it doesn't make much sense that those virgin MCs, that never shown any libido at all during the story, can possibly satisfy the girls after they have being already corrupted and used to way more experienced sex with the villains.
TL;DR: Multiple endings choices are nice, but some may make no sense in the story. In an unavoidable-NTR game, I usually always prefer the most NTR ending possible... Call me a fucking degenerate. =)
