I have seen you misjudge the intentions of a few of your students before, and have often wondered why you can't see their ill-intent clearly?
And I have often wondered how you think you can see it? Here's why some intentions articulating as actions are more easily missed — even if one is looking for them, which I was not, because that was not part of the role I played in my relationship with my students.
Short term dysfunctional or duplicitous agendas, are not very hard to gauge. In fact, they're right in one's face. Most advanced beings like my students, don't play these short term games. Their life's gameplan (call it a self-designed destiny) is usually designed to accomplish what they aim to do, over a longer period of time; the scope of a lifetime.
Then there are very advanced beings, or beings that have non-corporeal allies, or beings that have access to black magic items or knowledge. Such a one has a self-designed destiny design (or gameplan with a specific purpose to accomplish) that spans multiple lifetimes. It can be accessed, but knowing whether that purpose is benevolent to others in their environment or not, is a very difficult and effort-consuming feat to accomplish. So how can you so blithely assume that anyone can easily know if someone's intentions are "good or bad"?
In September of 2009, I was absent for a month, because I had undertaken to trace the agenda of Jesus Christ, which I could only see if I studied it from before the birth of this universe even took place. His life's mission or agenda, was that large in scope.
I respond to what's my allotted daily portion of life unfolding to respond to, and nothing more. I cannot allow myself the folly of judging the origins and worth of others' actions. I am only responsible for my own.
I hope this answers your question.
