“Honestly, my thoughts on becoming a Marine were nothing, but reinforced that day. What I saw was complete and total malevolence — bad overcome by good,” said Bialy.

“It’s a battle as a parent — you love your child more than anything in this world,” Brad Bialy said. “At the same time, you understand what he has, you have to share. It’s not really our choice anymore, he’s one of those people… they have to share what they have.”
