That depends. Do you suffer from schizophrenia? Did I provoke you? Was it an accident? There are a lot of circumstances under which I would not blame you.
If you punched me without provocation, with no evidence of mental illness, and did it "deliberately" [1] then I will "blame" you because that's the only way I know of to defend myself against future attacks.
[1] Note that "deliberately" in a world without free will just means "as a result of unknown causes inside your brain". The more we learn about how the brain works, the fewer pathological behaviors can be labeled "deliberate". "Free will" is a sort of "god-of-the-gaps" if neuroscience.
