Indeed, I agree - unless you live in a society that has no death-penalty (because simply imprisoning people for certain crimes - like murder, [censored] and treason - is not enough!), in such a society enslavement should be an option (if the person guilty of such a heinous crime gets to live, they should have to do it on societies terms: Meaning they should become the servants of society and do everything: From hard labor to serving someones drink and doing paperwork (whatever is needed more or less))

ps: That's my gripe with the law in Germany (I live there!), we don't have an adequate punishment for capital crimes (and German prisons are a holiday resort compared to most of the world's prisons!) -.-
