Puck also seems to know about sins, including Subaru's. He just turns a blind eye to it because Subaru seems like a nice kid. Didn't it seem odd how attached Puck was to Subaru? It all makes sense with his conversation with Subaru before killing him that last time. Puck knows a lot more than he let's on, and he might be getting close to Subaru to keep an eye on him. It'd be odd for him to leave Emilia in Roswaal's care if the utterly suspicious guy is actually suspicious.
I think Ram just mistook Subaru's force, which is made up of Emilia's enemies, as an attack group. And coz she inherited all the bad genes.
