When you link a character to crimes they don't commit, they get associated with those crimes. You guys are putting him in the same breath as rapist. Logan helped his Girlfriend take a boat because she was sad and got that Moby Dick quote stuck in her head so needed to take to the seas.
As for Logan's arc, you can tell Amy disregard s7 for him. In winter s6 she said, "Logan is a kid whose entire life has been preplanned for him. Rory grew up in a household where it was like, ‘Anything you want, kid, you go for it.’ He never had that. He grew up with all the money privilege, but he didn’t grow up with any freedom. His freedoms are sort of self-imposed, ‘I’m going to go act like an idiot, because I’ve never gotten a chance to explore who I am.’ ".
And in 2016, she said, "This is a boy who has never been released from his family. And all the freedom of the money and the wonderful charm of the Life and Death Brigade and the fact that he has cars and can do…in his heart, in his soul he’s incredibly trapped".
