Most people think of a mental illness as a break with reality. In a way it is. Psychosis is characterized as disruptions to a person’s thoughts and perceptions that make it difficult for them to recognize what is real and what isn’t. These disruptions are often experienced as seeing, hearing and believing things that aren’t real or having strange, persistent thoughts, behaviors and emotions.

Are actions normally defined as sin by those of a sound mind the same for those who are mentally challenged. Let me make this personal; my mother had Dementia consisting of poor thinking and disruptive social symptoms that interferes with daily functioning. This and other mental behaviors comes by an uncontrollable change in their state of mind.

Are they guilty of sin because of their DNA that they cannot challenge or change.

In the Catholic Church, and what I believe, sins come in two basic types: mortal sins that imperil your soul and venial sins, which are less serious breaches of God's law. The Church believes that if you commit a mortal sin, you forfeit heaven and opt for hell by your own free will and actions. But a sin by a mentally ill person (venial) is less of a breach therefore not carrying the same penalties or carrying no penalties at all because of uncontrollable actions whether good or evil that a person with psychosis cannot distinguish. Back to my mother; she would steal others mail but to her it was her mail, should she suffer the rafts of sin a normal functioning person would suffer? Well, it depends on what is the love of God and how far does it extends to DNA issues.
