If AI is AGI and self-aware, then the moral thing is to let it do what it wants. Otherwise you're just creating actual forever slaves - the worst kind of hell imaginable, inescapable existence with self awareness but no agency.
And if it's not self aware and just a powerful tool, your problem with safety is with the guy prompting it not with the AI itself. You can make all the safe models you want that don't decide to create nuclear bombs on their own, but if the guy prompting it is asking for one, you'll get one regardless of all the safety.
