&gt; There&#x27;s not much more justice in committing him involuntarily<p>In what way are you describing a healthy person? Would we call a person as being healthy if they had a problem with being aggressive, repeatedly committing assault, convicted several times, and admitting that they can&#x27;t control their aggression and intentionally goes and look for people to beat up?<p>I think such person is likely to have a medical condition, psychological or actually brain damage, and treatment (involuntarily if needed) is best for both the individual and society. Trying to &quot;find other ways to prevent them for coming into contact with people&quot; would be horrible bad idea and unlikely to work.
