I don't think punitive damages are unreasonable.
My thought has always been that the civil courts should be for redressing provable loss caused by non-criminal fault - where one party has lost out because of some failing of the other, like not paying what they owe, breaching a contract, etc. A matter of arbitrating differences between people if you like. I don't feel they should be used for punishment; with their lower standard of proof, it always seems to me to be a run-around to avoid the higher standards of the criminal courts. If someone or a company should be
punished for their actions in addition to redressing any specific loss caused, in my mind that is the remit of the criminal justice system, not a lawsuit. I am well aware, however, that the US legal system disagrees! Here punitive damages exist as well, but are much much rarer and can only be given under some pretty specific and tight circumstances.
I'm no expert on English tort law, but I know that he have vicarious liability to at least some extent. For example, if a case involves the actions of police employees, the case is cited as
The Chief Constable of Whatever Police vs. John A Smith.
