Yes, all of this. I'm mentally ill myself, and have hurt people as a result of that mental illness. I have also been hurt by other mentally ill people, including my parents, going back to my earliest memories. The question of how much culpability mentally ill people have for their actions is one of the Issues at the core of my family. Because it's complicated! But it's definitely not a question you can just brush aside by saying "People are responsible for their actions".
