No, Kapusta, that’s where you’re wrong. At least when you would equate a murderer with someone who has a “mainstream” mental illness. They are not the same, and one is not necessarily mentally ill in the clinical sense when they commit murder. There may be other factors involved such as past experiences, events in his life which have made him callous toward human life, etc…but just because a person does something unspeakable which you cannot explain does NOT mean that they must be mentally ill in the clinical sense.
As I said, to the best of my knowledge, Levi had no history of mental illness. I understand that it is easy to blame what he did on a mental illness, but you’re just wrong about that. Thought you should know. As Aries said, he wasn’t mentally ill, just evil. There is a difference. Now he may not be wired the same, much in the same way that I am far less emotional than your average person, does that make me mentally ill? No. It makes me different.
