Why do ex-convicts return to their previous doings after getting out of jail?

Jail/prison changes people. They may have been rough before they went to jail, but once in jail, they will get worse. For most who end up in jail, life on the outside is very, very hard. They can't pay their rent, feed their kids or themselves, can't meet their responsibilities in general. Once in jail, all of those things are taken care of. No more worries about where the next meal is coming from or is the electric bill gets paid. No more worries about medical care. No relationship hassles. No responsibility, period. They learn how to be tougher, and how to work the system in the jail. I truly believe that once they get out, jail doesn't seem so bad anyore. It is worth it to steal money for something they want or need on the outside, because if they get caught, it will be there for them in jail anyway.

When someone becomes a convict, society will start having negative view on them. They'll see that person as a criminal and only bring harm. He/she might already change when they're out of prison or been in there not by their fault but society will never see them that way. They'll reject ex-convict and this will make it hard for them to start a new life. Some might surrender under this circumstances and will turn back to their previous doing in order to survive. Of course, some never learn and been in prison because of his/her fault.

Some of them learn form their mistakes but not all.Infact after going to jail they become more and more cold.They start thinking going to jail is not big deal at all.Thats why they dare to do those crimes again and again.
