I feel like the writers and editors should know. Years back there was more of a sense of consistency where now characters can change on a dime based on who's writing them. I didn't agree with that statement about Jason not being written well in years either.
I was more or less mentioning it for the irony of Tim previously trying to kill his dad's murderer but even in New 52 Tim to pre-Tynion he wasn't written like this. Tim knew multiple ways to handle a situation and didn't condemn Jason for what he did. Jason still killed when they started acting like brothers. Tim tired to understand why and knew others didn't. He wasn't written as someone who's shocked at the very notion of Jason being part of a family meeting.
