Several things Ash has done have struck me as off.
First, there's the fact that he's angry at town for directing what hider does, yet he's doing that more than anyone else. He's directly saying that the hider should hide behind their town reads. This increases the probably for hider doubledeaths more than anything else.
He's saying the risk of hiding behind scum reads is that the hider could die without letting us know who they hid behind. But that's the exact point of the plan! I think finding scum is MUCH better than making an IC, personally. The problem is simply that it's so hard to communicate the scum target if the hider dies.
He's saying that "I think this is a bad idea, and since I love ideas like this but hate this one, you all should stop, now." I don't think it's a bad idea, and given that 2/3 of the town agrees, I think Ash's unwillingness to even consider the plan is anti-town at best, and scummy at worst.
Also weird, is that he's brought up my quote from the beginning of the game multiple times, and finds it scummy, yet doesn't make me a scum read when it's really all I've contributed so far today. It's weird that he's going after people for the plan, yet doesn't find the first person to mention a plan scummy.
Finally, I'm not buying the "make me the lynch, screw it" argument. He KNOWS that that lynch isn't going to fly. He knows it. There's absolutely no way we'd lynch on that basis, as people would probably be policy opposed to it. It's a great way to be the first wagon of the day (first wagon of the day almost never goes through), which then allows you to avoid suspicion later. Scum!Ashersky knows that the lynch just doesn't happen, so it's not a risky move.
