i think its just about "judas" betraying his friends in general
he regrets it and every one is saying bad things about him but deep down they know they would have ended up doing the same:
"and they've got a smile for you
no matter what they try to tell you"
and "judas" just wishes he hadnt done it and the stuff hes put himself through and thinks about himself is much worse than what there saying:
"nothing they can sing about can match those things you put you through"
