Except it does give credit. Take Sirius. He was accused of killing Ginny and he claimed overager vigilante. That was adapting to the situation. If you are a bad guy, being fixed on one roleclaim throughout the entire game is a lot harder to pull off. Imagine if he'd been gearing up for a cop claim - how could he have explained killing Ginny?

Any further questions about my role or claim?

It was a bit odd that Sirius died. We'll see what Buckbeak says.
