I don't think you talking about ethics with him would bother him. It's me, and it dragging up our time with my foster-father. Ren had a difficult relationship with him. I know he loved Ren but the two of them didn't always get along. Ren's got a lot of things to unpack about that now that his uncle is gone, so it's more like 'don't rub the sort of discussions we had with his recently-deceased uncle in his face'.
And I get a lot of that stuff. But, like, what if you had something unique to offer? For instance, healing someone, if you could do that? Now, for one person, versus later. What if you get thrown into prison if people found out you could do that? I'd heal someone to save a life and take the risk, I know that. Or if it was something special that I could do and I wasn't sure anyone else could help, I'd take the risk. I think Uncle Luke, my foster-father, would have been more conservative. But I think he came to feel that way because of his own experiences, and I don't know what all of them were or why they made him feel that way. I know I'm more like you in that respect.
