Lobotomy was used for this purpose for many years to make unruly prisoners docile. The practice is still legal (and doesn't use an ice pick any longer), however it is rarely used today. There are however an array of medications that could be administrated to force compliance and do not cause a permanent state like a lobotomy would. But yes, the entire idea is dehumanizing in my opinion.
