Years back, I had a coworker who was showing of some nude pictures on his phone. We looked at him and said "who is that, and why are you showing us? And we hope it's no one we know." He replied it was his Fiancé. We told him he was an ass for showing something intended for his eyes only to other people. He blushed, and looked like a kid who had been caught doing something wrong. I think he realized it was not cool, and his peers expressed their disapproval. Made him realize he was being a jerk.
That being said, I think he was trying to show off more than trying to hurt anyone. He was called out, and was told off for being an idiot and very immature. He never did it again that we were aware of.
Do I condone what Logan did? Absolutely not; it's betrayal of confidentiality, and that's a mark of immaturity and selfishness. I believe he was mandated some classes to address the lack of compassion and insensitivity to what he did.
At the same time, I don't believe he's done something that warrants him from being banned from making a living doing something he's good at.
He's got to live with what he did, and he will almost certainly get called out on this by his peers. And he deserves to be.
That being said, I sincerely hope the girl involved in the incident has gotten over it, and is coping okay. She should feel no shame for what that happened. Betrayal, but not shame.
