It's interesting how this guy's jacket can feel powerful for us but actually here it doesn't matter. Most people can't read it and if they could they wouldn't know what Lucifer' means. 6's are lucky numbers so 666 is a good thing. No one knows the significance of the number. 444 would have been far scarier to most. He's just a skinny college aged kid wearing a 'cool' jacket. Not a scary guy at all.
