Iron was recently arrested for beating his girlfriend, and Yoon Byun Ho expressed his distaste on Facebook. He wrote, "I don't care if you do drugs or fight other people on the street, but if you hit your girlfriend, you're an empty-headed dimwit. You pretended you were the coolest guy around, but you're pathetic. If I did that, my mom would have killed me. I didn't get raised sh*ttily like that. You should sincerity repent, you f*cker."
