I thought that was the intent, but all the other posts made me unsure of myself.
So the first one I'd like to bring up is the game Crystar (which is where my pfp is from. Its one of those games where a lot of sad things end up happening. For example, the game has an option where you can pet Rei's dog, Thelema. Thelema dies about halfway through the first timeline and it goes downhill for a long time after that
There's also Tales of Xillia 2, specifically the Julius ending. in this ending you refuse to sacrifice your brother to open the way to the final dungeon and stop Big Bad. Naturally all of the other characters disagree, telling you to see reason. But if you refuse... Instead you fight the entirety of the Tales of Xillia cast alone, in a game where combat is based on pairing up.
Your reward? An ending where you take your brother Julius back home through an empty town, fully aware that you personally killed all your friends and doomed everyone in the main timeline.
