I think the whole thing about the apology not being sincere is a little bit out there. The victim literally requested for the apology to be written. The quote, ""The woman said she asked that Mailloux send her a sincere apology in written form because she did not want to meet with him in person." Written words are all subjective to the reader. Logan Mailloux probably would have prefered to communicate his apology verbally, but he wasn't going to go against the request of the victim who he harmed. Written language cannot communicate sincerity as well as verbal language. You can't hear tone and other inflections that would have conveyed what the apology should have conveyed. Obviously, I would like to read what he wrote to her, but I doubt that will be published, so we will never truly know. Mailloux apologized publically many times and apologized to her in private. If that's not enough, she and her family should meet with him in person or at least over a zoom call or something like that. Maybe the apology he wrote privately wasn't enough, and if so, that's a dick move, but he was put in a bad spot if that was his only method of communication. I doubt he knew her address (for sending a handwritten letter), email, or anything of the like, and I highly doubt the victim would want him to know that after what he did, so text was probably just a safe bet.
I don't know though, maybe I am in the wrong here, but text is so subjective. You can give two people the same written words and get two different meanings out of them.
