People ought not even to be allowed to suffer for the consequences of their own folly, and should be punished for it severely if they did.

Context

“I was more than once misled by these plover-like tactics, and on one occasion was near getting into a serious scrape. It happened thus:— A man of venerable aspect was maintaining that pain was a sad thing and should not be permitted under any circumstances. People ought not even to be allowed to suffer for the consequences of their own folly, and should be punished for it severely if they did. If they could only be kept from making fools of themselves by the loss of freedom or, if necessary, by some polite and painless method of extinction—which meant hanging—then they ought to be extinguished.” source
