This kid was a mess but you can't blame his fellow students for avoiding him.
"Items recovered by police at the scene included gun magazines with swastikas carved in them. One student reported that Cruz had drawn a swastika and the words "I hate [n-word]" on his backpack.[77] CNN reported that Cruz was in a private Instagramgroup chat where he expressed racist, homophobic, antisemitic, and anti-immigrant (xenophobic) views. He said he wanted to kill gay people and Mexicans, and talked about keeping black people in chains. He said he hated black people "simply because they were black," and Jewish people because he believed "they wanted to destroy the world". He also referred to white women who engaged in interracial relationships as traitors.[78]
A former classmate said Cruz had anger management issues and often joked about guns and gun violence, which included threats of shooting up establishments.[9] The brother of a 2016 graduate described him as "super stressed out all the time and talked about guns a lot and tried to hide his face". A student who was enrolled at the school at the time of the shooting said, "I think everyone had in their minds if anybody was going to do it, it was going to be him".[79] A classmate who was assigned to work with him in sophomore year said, "He told me how he got kicked out of two private schools. He was held back twice. He had aspirations to join the military. He enjoyed hunting."[65] A student's mother said that he also bragged about killing animals. A neighbor said his mother would call the police over to the house to try to talk some sense into him.[80]"
Let me ask you this: If you had a kid that went to Parkland would you encourage your child to befriend this kid?
