How messed up are teachers !?

A particular incident from when I was in 1st grade weighs heavy on me sometimes . We had a female teacher who was quite violent with kids . One day , while we were all in our class , being taught by someone else , she entered along with a fellow classmate of ours from another section , had his pants down and his backside out , to shame him infront of everyone , which I am sure was for no major reason , because we were literally kids , 6-7 years old !! So what if he hadn't done a stupid homework or was talking in the classroom , did he really deserve to be shamed like this !!!

I am not sure if that kid complained to his parents or not , because he did the leave the school in next session , and the teacher wasn't there for long after either . But this just goes on to show how disturbing schools used to be and maybe still are . I remember parents of a different kid telling the teacher to beat him up if he doesn't study , etc. at a PTM and how the teachers actually did it , which was just a way for them to take out their frustration .
