Quite likely. If one gets infected with rabies, he has an incubation period in which he shows no symptoms. When symptoms begin, he will feel some flu-like symptoms. Then comes the bad brain symptoms, with some erratic violent behavior plus foaming at the mouth, and death some days later from paralysis and coma. The flu-like symptoms can last days to a week or so, and the rabid behavior another week or so.
if left untreated. Yes it can lead to violent-like behavior.
Yes. But then you will die quickly.
