Are you autistic? He was. Also, when you have been traumatized or abused at an early age, it stunts your emotional growth. Especially depending on the severity of the abuse and when and how vulnerable the individual was at the time.
RIP Cho, finally
If he was autistic, he might have been unable to communicate well. Many autistic children have feelings of inadequacy due to their inability to socialise and feelings of being different.
And yes he was picked on a lot at school for his shyness and mumbling.
BLACKSBURG, Va. // Long before he boiled over, Virginia Tech gunman Cho Seung-Hui was pushed around and laughed at as a schoolboy in suburban Washington because of his shyness and the strange, mumbly way he talked, former classmates say.
Once, in English class, the teacher had the students read aloud, and when it was Cho's turn, he just looked down in silence, Davids recalled. Finally, after the teacher threatened him with an F for participation, Cho started to read in a strange, deep voice that sounded "like he had something in his mouth," Davids said.
"As soon as he started reading, the whole class started laughing and pointing and saying, 'Go back to China,'" Davids said.
"There were just some people who were really mean to him and they would push him down and laugh at him," Roberts said. "He didn't speak English really well and they would really make fun of him."
