I imagine a year in solitary confinement (how is solitary even legal still?) would likely change your mind. I'd say no life is better than a life of torture, and taking "life of any quality is infinitely better than no life" to the extreme, would mean that hell with eternal constant torture would be better than not existing, which I can't agree with nor understand. I'm glad that you have such a positive outlook on life, but I doubt that you could maintain it in the face of a long torturous experience, few can.
