Wow, Taebin turns out to be pretty pathetic. It seems like he had all the clues about what DICE are but he either decided not to share them with Dongtae or didn't really understand them.
The DICE don't just change skills. That's the bait. They change who you are. That's the hook.
Dongtae is definitely young and naive but he also doesn't know what we do or what Taebin does (because the D-bag didn't tell him). The DICE clearly are more dangerous than he ever could have realized. I always assumed the main danger of DICE was the inherent flaws in people. Like one of my favorite quotes.
"Nearly all men can stand adversity, but if you want to test a man's character, give him power." - Abraham Lincoln
But now I think maybe that's wrong. It seems like it's a trap. The DICE lure people in. Changing them bit by bit. Until they're not human at all. In other words the more they change themselves the less of the original person is left.
