Is this a true contradiction though? Depression, anxiety, and even schizophrenia don’t disable the person’s free will so absolutely that they loose all responsibility for their actions. It makes sense for someone to treat depression as an illness and separate their moral self from it, because there is so much of it left. I doubt people would say the same about victims of brain damage, who are unrecognizable from their former self, don’t remember anyone and react aggressively to everyone, including loved ones, because the parts that made them who they were no longer function and will likely never function again. It’s hard to say that a person in such a state has any responsibility for anything.. but it’s also hard to say if they are still a person. I think our definition of a person involves some level of moral responsibility, and our sense of hope depends on it. If moral responsibility is gone, the person is gone. It might sound harsh, but I only speak from personal experience. I always felt that my grandfather died before his body did – the latter kept going a month longer, terrorizing the family.
