I'm going to get a whole bunch of kids suspended and one kids expelled
Why would you want to get these children in trouble?
I think I represent the society and public order. If you break the rules, it will cost you so dearly
Whatever they have done may not be an offense worthy of expulsion. Discussing their behavior with them or their parents might be a better option.
If it's good for society, then it's okay.
Getting children expelled from school might not be what's best for society. That just gives them time to run amuck with nowhere to be.
