The person I know who is the most concerned with whether other people are being sneaky, and sees (and condemns) sneakiness in everyone, is also the sneakiest person I've ever met.
This is a pattern I've noticed in many things.
The person who hates cheating the most is probably the biggest cheater.
The person who believes everyone else is lying is probably a liar.
So, recognizing this in others makes me examine myself more closely.
I don't like archation in others. Does this mean I am prone to archate?
I know I have the capacity. I've done it more times than I want to admit. I do believe I am getting better at not doing so. When I feel the urge to archate, I notice and stop myself-- in almost every case. Sometimes, I notice after it has already happened, and then I am ashamed of myself. If I can, I apologize.
I know I am capable of being a monster, and life is a constant struggle to not act it out. I suspect that is just part of being human.
If I do archate, I want people to call me on it. Unlike the sneak, the cheater, and the liar, I am willing to face my flaws. That doesn't mean it's not uncomfortable, or that I will take it well when it is pointed out. But I try. I want to be better than I am.
