Yeah, this is a question that doesn't get brought up nearly enough in discussions about generation ships: is the entire concept unethical? You're condemning multiple generations currently unborn to spend their entire life in a can. And even once they get wherever they're going, it's probably going to be a barely-habitable frozen rock much less pleasant than Earth. Kim Stanley Robinson's novel Aurora talks about a bunch of this. Robinson mentioned that he was tired of talk about generation ships avoiding the biological, social and ethical factors and just focusing on the physics and technology, when those are probably the easiest bits. Highly recommended.
