It obviously takes some intense sacrifices to get to the top, alot of which have been discussed numerous times here. But besides for example the possible sacrifice of Taes grandma, its scary to consider that bts being up there with these people would mean they have performed other sacrifices/rituals (such as p***philia and probably one of the worst, human trafficking). I'm not saying they've done this but honestly, we sadly can't rule these things out.
The speech they did today which obviously appear to have good intentions, whilst it may have been so, what if as another member suggested above it is just to expand their brand and get bigger henceforth further promotion for the elite. The rehearsal of it all provides an indication that these might not even be there own words, as its clearly scripted. Which is understandable but it does lack authenticity which is something I've always admired about bangtan and sadly, as they get bigger, the authenticity seems to decrease. Long story short, i got puppet vibes from their speech. But thats just my opinion.
