The tailor lies on the ground, his hair and clothes burned to the ground. When the phone explodes, he jumps backwards like he could and covers his face with arms. The kevlar blasted his life. But that's all it was. The tailor says, "screw the mission, screw the guys who are going to hell" . The self-destruct button on the phone is so powerful that even his body armor couldnt stop it. Remember when he asked Kim to hand over the phone, but Kim refused and insisted that it be presented to Kim himself? Isn't that karma?
