It is mainly (or only) the slaves who kill for the Utopians, but it did not require any killing to become a slave. In fact, "the most serious crimes" (unstated, but clearly not only murder) are punished by "servitude" (slavery). "If slaves are rebellious or unruly, then they are finally slaughtered like wild beasts that cannot be restrained by bars or chains." On the other hand, if they are "tamed by long suffering and show that they regret the sin more than the punishment, their servitude may be either mitigated or revoked, sometimes by the ruler's prerogative, sometimes by popular vote."

These statements occur near the end of Book 1, which began, after some preliminaries, with a conversation about the justice of the death penalty for theft. (In an endnote on page 145, Miller tells of a report from 1587 that "in the reign of Henry VIII alone 72,000 thieves and vagabonds were hanged.") Hythloday believes that theft is a necessary consequence of personal property. Unstated but evident is that he believes also that personal property is not only a sufficient condition for theft (which makes theft a necessary consequence of it), but also a necessary condition for theft (which makes theft contingent upon it). Removing personal property, then, removes the possibility of theft, he believes: with the unexamined assumption that you cannot steal what you already own in common with everyone else. But of course you can: you take it and keep it for yourself so no one else can use it, taking what belongs to everyone, and not sharing it with anyone. Only the coercion of others, through established law or otherwise, can alter this. But then you are back to the existence of theft and social restraints to admonish and respond to it.
