In this case I think you're half wrong. The Law is "do not seek knowledge or power from beyond the outer gates." A literal reading of the law would indicate that the intentional acquisition of Outsider knowledge, even by a non-spell slinger, is enough to get your head chopped off, but no amount of villain's exposition would put you in similar danger. Now, if a person is told something truly earth-shatteringly dangerous the Wardens might kill them in a carefree, off the books, "oops, he must have slipped and fallen on that sword, what a tragedy" sort of way.
I don't think the Lawbreaker power is assigned unless a character actually employs knowledge or power from Beyond using magic.
