Which is the proper choice Go to Juvenile justis system or adult jail?

I believed it is not appropriate to prosecute juvenile to juvenile Justis system when they offended serious crimes. I thought that they should be prosecuted to adult jails to experience the painful hardships to be able to realize the depth of what they did since adult jail is more strict and terrible place to have compensation. However, the article of PRO enabled me to what is the most important thing to need to be done to keep community safe from Juvenal crimes is. The important thing is not to punish the young people, who did crime, with strict and violent way, but is to try to treat them and make their mind to enable them to grow up as a mature person when they go out from there. Therefore, there is a fact that young people who went to prison as a adult is more likely to be dangerous when they came out than when they went in there. It is not necessary that a rigid and painful hardship in adult jails for Juvenal's can keep the safe community's. I think punishing young people, whose brains are under growing, with abuse is no use. I am considering that it is the same thing as teaching math to babies.
