How he will improve his lifestyle whenever released to go home?

His lifestyle is only going to change if he does steps necessary to improve his thought process. There is something that the therapists point to when assisting in rehabilitation: criminal thinking. Does your inmate have the capacity to look at himself and his flawed thinking. The inmate that can come to terms with his mistakes and face "change", will change. There are also other attitudes that an inmate must address as they go back to be a productive member of society - things like honesty, caring, objectivity, gratitude, humility, responsibility, open-mindedness and willingness. Change is up to the individual but if he wants to, it's up to him to accomplish it.
