But you always have free will! Yes, there may be people trying to bend you into doing sth against your will but till the last second you have a choice to say no. Just as
@deniiiiXD's example above. If you trust in God and want to be with Him, it'll even cost your life. But the moment you choose to save your life, that means you prefer the things of this world. Those boys simply don't want to just do music and "express" themselves. If they wanted that, they wouldn't go into such companies that put you in a frame. This is hypocrisy! So it clearly shows you what they are after - fame and money. This is what they want and they keep pushing themselves wilfully into this. Personally, I don't believe that mk ultra exists in such form in kpop. They just tell you you have to work hard to succeed. I recently watched the first 2 eps of Yg's new show and you can see how it's done. After spending years into this, they just don't want to leave because they'll look like losers in their family and friends' eyes. Aka they look for the approval of this world. And how does the world judge you as successful? Well, you're considered as such if you are a boss, have the highest authority and even be on TV. And believe me, they want all of it. Just because you see them tired, doesn't mean they want to be out. Actually, they exhaust themselves for their own striving of the things above. There's no such thing as them not having a free will. They have one constantly!
