What would 당신 do?

There was this guy who took your best friend hostage and 당신 know exactly who he is and if 당신 successfully 신고 him to Person A he will definitely be stopped. If 당신 dont 신고 him, your best friend will be tortured and then killed.

Although the catch is that this guy seems to be able to have an eye on 당신 where he knows everything 당신 are doing and saying 75% of the time. If he notices 당신 doing anything funny like reporting him, he will not only kill your best friend, but 당신 and several innocent people.

Would 당신 take the risk of reporting him?

And dont give me the flaws in this. Theoretically speaking that there are no loopholes to this 또는 anything. *wrote this late at night when I was getting ready for bed*
