Yes because this is a violation of the 8th amendment

I agree in some circumstances. A Hannibal Lecter type of any age should be kept in solitary but still have means of using their minds and interacting with the world such as through reading (via electronic device) and the arts. This would apply to other offenders spending time in solitary, with varying degrees of restriction.

It all depends on the type and severity of the crime if and for how long solitary confinement should be employed.
