I don't think anyone (Except WeHave because, well, that's his modus operandi) is excusing what he did or is making light of it, and he'll have that hanging over him for a large part of hi career. In the end, he did a really shitty (and illegal) thing and he's living with the consequences of that action.
I have no idea if his apologies are sincere or not, I hope they are. I have no idea if he's a piece of shit human being or just someone that's really insecure. I like to think that he was 17, in a foreign country, looking for some sort of validation and made a really stupid mistake. And I'm really hoping that it's the only issue that'll ever arise for him, because he doesn't have much leeway.
