Midnite your classroom sounds amazing and my son, with autism and challenging behaviour would thrive.
He currently has a teacher like you and it shows.
So perhaps the issue here is not the children but the adults; teachers, parents, policy makers, commissioners...
Though children do impact upon their own environment the very nature of them being children means that ultimately it is the adults that guide, inform, and influence them and the environments in which they develop.
And it's not just me, some randomer on the internet who says that but decades of ecological theories of child development that say it.
If you construct an environment where positive behaviour is rewarded, their needs are met, they are nurtured, they are equal and their achievement celebrated then they will develop emotional resilience, their wellbeing improves and their behaviour follow suit.
Again decades of ecological theory say so... Theory that underpins social work, health promotion, child development studies, assessment of the family..."
Or alternatively create an environment where their is a hierarchy of children; those who are superior are quiet, good and submissive to the rules of the adult in the room regardless of their own needs. An environment where, arguably no one really has a voice because they the consequence of speaking out is being sent to the naughty room.
You will soon be a position where the 'good' children begin to see themselves as 'superior' and start behaving as such to those children who are not their equal which more than likely would escalate the behaviours and reinforce the stereotype.
Institutional bullying...
Your thinking OP is not just misguided - it's downright dangerous.
