I don't actually hate Sid because I can definitely feel it that this betrayal of his isn't as simple as that. I feel like there's really more to it. But I really really don't want him to end up with Jin. Asides from all the tremendous shit he has done to Jin, it's pretty clear that's it's very one-sided.
Anyway, (SPOILERS) Jin pretty much has his destined lover. It's quite nice, given their history. As for Sid, I feel like there's a possibility that he will be paired with a future character that looks like a darker fraternal twin of Cain. He's one of Cain's subordinates, has a legion of demon dogs whom he really cares for, and has a whip for a main weapon. I want him to pair up with Sid and you know, "punish" Sid for being such a bad little albino demon.
(SPOILERS: Sid's betrayal is in fact is not as simple as that )
I love Sid but I have no idea what’s going on between him and Satan like I get that he was Cain’s right hand man and he was indebted to him but then betrays his to fight for Satan (I think that’s what he’s doing now???) but I don’t get the deal he made with Satan or what the little eyeball thingies are cause in the earlier chapters I thought that they were taking over his thoughts/body and making him more evil when he’s really just a sensitive broken baby but now I have no idea....also I want him to end up with the best friend (I think his name was Jin?) I hope things make more sense later
