Someone who is bullied tentatively is affected on a physical and mental level. The psychiatric effect abuse has on the mind is known to kill and severe the bonds between certain muscles. Whether its oral or verbal, a victim is affected tremendously. The bully is doing it as a form of escapism. He feels he is not safe in his own skin, and targets a weaker demographic. This is a bit of a superiority complex, as he/she believes they’re better than them and relentlessly target them. Safest bet is that a bully will have some sort of PTSD in the future.
