From what I've seen on this thread, most people are worried about K@i because of the symbolisms related to Obssession MV (like someone posted before, during his screen time he has a "drained color" which could indicate a corpse). The MV as a whole is full of symbolism point out to satanic sacrifices and mind control (which other EXO mvs have such as Lucky One and Kokobop).May I ask why you believe Kai will be sacrificed,are there some signs? I'm not questioning your theory btw since anything is possible with the elite, sadly, but now I am genuinely concerned for him too, I know he is in the occult but he is my favorite in Ex0(off-stage) and I actually find him one of the most quiet and kind members in kpop in general, which is rare, but of course I can be wrong since I don't know him at the end of the day.
But in terms of his life out of EXO concepts, I think he could be sacrificed also based on his trajectory until here. He had not just one but two dating scandals. SM could have shielded them if they wanted but they didn't. Why? Also, the context of both dating scandals are similar (he's at the parking lot with the girls, in a way he could be seen). Again, if he learned from his first experience he would do everything he could to not be caught again. but it didn't happen. Why? I mean, there's a lot of other idols who date and the public never knew and they even share techniques of not being caught (going out with groups of friends and stuff). So why him?
For me it could be a "humiliation process". Especially in 2016, he had a bad year with lots of injuries, a dating scandal with lots of rumors sexualizating his relationship with Krystal and at the time he didn't have schedules like the other members did. And this considering he was one of the most promoted members of EXO when they debuted. So, why? His career got better, he got more schedules but then he was caught dating again. His father died last year (someone he treasured a lot) and he keeps reacting more aggressively when he makes mistakes. Also he mentioned in some interviews that he had depressive thoughts. Maybe all of it could be "hints", adding this new comeback, of a future sacrifice involving him?
I really don't know, but I honestly go to Allkpop every day because I feel fear in my heart. I fear that someone will have the same path as Sulli and Hara, especially someone like Kai/Jongin (I personally love him as well). I hope nothing bad happens but after everything, I just expect the worse.
