Nah, that way of thinking is wrong. Schools are there to teach academics, thats it. It is the duty of the parents to teach moras and ethics. That's why these parent teacher conferences exist, if the teacher identifies what they view potential issues with the student's morals or ethics, they inform the parents so that the parents can make a decision on the matter. In this case, the parents agreed with the teacher's assessment and gave her permission to take actions to correct such behavior. The only time a school is allowed to take disciplinary action on their own initiative, is when a student has violated the school's rules, and only because the parent gave them the permission to do so when they chose to enrole them in that school. (Large part of the reason why school choice laws need to be implemented instead of forcing them to attened a certain school, if they cant afford private or home school. Also why i have no sympathy for when a child or parent pitches a fit when they get punished for violating a rule at a private school, no mater how stupid you think it is, its the school's rule and you chose to admit them there, its on the parent to research the school and chose the one with policies they agree with) )100% control should never be given over to schools, schools being given too much control is what has been causing a lot of problems in the u.s. today because there are a lot of schools and teachers that view it as their right and duty to shape their students moral values to their own liking regardless of what the parents belive or wish for their child.

If your parents are the king and queen of a country that's kinda hard to do cause they'd be busy leading and dodging political backstabbing of the opposing nobles.

Sorry, but there's a difference between schools teaching intermediate and advanced morals/ethics/manners as part of their normal academic education, and schools having to re-educate all the basics of how to behave around ppl because the narcissistic and spoiled brat's rich parents missed to teach him that his position doesn't mean that he can treat everyone else like laws and human rights don't exit if it's him breaking them...
the first one is what is part of the school's purpose, the second one... there are specialized institutions and schools for that... and I wouldn't be surprised if teachers there get paid an additional hazard pay...

Considering that their kid bullied ppl, injured multiple students and attacked a teacher, they should have just made up some random long lasting illness and took that ticking time bomb out of school, put under house arrest and later admitted to a school for problem children instead of pushing it onto the very teacher their kid attacked... but no... to 'save face' we gonna continue to cause problems to the entire school...
