Hypocrites?

Most people say that it's not right to judge people no matter what, but are we hypocrites? Yet, we say it's wrong to judge as people because no one is better than the other but we give no mercy on judgements for serial killer. There's no holds bar for these human beings, or no understanding, for the public perspective in America. Our courts and government may give the defendant a fair trial, but do the citizens of America? Can these human beings, if found not guilty due to mental disfunctions, have a chance at having a decent lives and are they able to start over in the publics eyes? I'm not saying we should let serial killers off easy, but if there is something seriously mentally wrong with the defendant shouldn't that citizen get all the medical and pschological help they need, or should they just be thrown in prison?
