I think that Blake is capable of using lethal force against humans and faunus (in fact I think that they all are, even Ruby). However, I think that Blake would be very, very reluctant to do so unless the situation was very bad. Her morality is what seperates her from radicals like Adam and the Triumvate and she isn't likely to be willing to give that up easily.

I think that's why Roman was so calm when Blake had a blade to his throat - he's dealt with enough killers in his time that he knew she was unlikely to be able to kill him in cold blood. In a fight? Well, that's another matter, which is why he didn't hold back with her.
