In high security and solitary confinement there are guards that will have to deal with them, and the inmates are afforded rights like visitation or recreation where they can gain contraband, make shanks, extort and assault inmates and other guards.

Inmates will pretend to or legitimately damage the cell or themselves to get guard attention and then assault the guards.

Study these issues further and you will find it's not simply a matter of putting someone in a single cell by themselves and now that's it, they can never harm anyone again.

There are elaborate criminal schemes that occur inside of correctional institutions.

Eventually, society will have exhausted every recourse in attempting to accommodate this person, and I say not to be sarcastic, but to present you something to think about, would you welcome a known serial killer into your home since you are so against killing them and there's no place left to put them? How much do you expect others to suffer and sacrifice for one criminal and your own perceived social justice?
