The Judge's have three roles, all of which kill in some way, but none of which are a typical factional kill. One of them primes targets on consecutive nights and then lights them all on fire. One of them infects targets with decay who die later (we'll get a report from the person infected if that happens). One of them only kills a person who visits them. One of them has only two kills (which cannot be prevented y Doc save).
Angles only kill if Mean Machine is activated, and in that situation it is optional.
Not a huge surprise there were no kills, and I think the only one that could have possibly been blocked by a doctor would have been the Mean Machine Angel kill.
