@OmSigDAVID,
The plaintiff you described lacked both a knowledge of probable consequence, as well as a sense of responsibility. The two most immediately obvious probable consequences would be that he won, and was therefore stealing from the defendant; and, that he would lose, and suffer adversely himself (at the very least, having the expense of a failed suit). He also, apparently, lacked a sense of responsiblity, giving no thought to who might be hurt by his actions.
When i was in the army, i opened my foot locker in the barracks one day to get a clean pair of socks (keeping clean, dry socks on your feet is important). I then thought that i should wash my feet first, and, looking around, and seeing no one else there, i went into the latrine, and rinsed my feet off in the shower. Having dried them, i walked back into the bay where my bunk was, to catch this joker going through my foot locker. I asked him what the hell he thought he was doing--his reply was: "Hey man, i didn't know it was yours." I resopnded: "You knew it wasn't yours! Who the hell raised you?" He got pissed and asked if was talking about his mama. I said yes. He backed down.
He also lacked a consideration of the probable consequences--in this case, either that i would be robbed, or that he would be caught, and might suffer adverse consequences. And, of course, he lacked a sense of responsibility.
However, i don't think that it is the job of schools to teach children a sense of responsibility, and i even doubt that they can reasonably be required to teach the consideration of consequences, beyond teaching children how to think logically. Teachers do well to give students the lessons of the curriculum. Responsibility and consequences are things they must learn in the home.
