If this is true (and I don't think it is), then we need a fundamental, radical overthrowing of the social order, and a lot of work put into constructing a new one. Any system where putting people to death is more "practical" than giving them fulfilling lives must be destroyed, and replaced. (It may be more effective to destroy and replace the system gradually – "reform" – since revolutions tend to have too many moving parts for Blanquists to keep track of, the situation has to be pretty bad before a popular revolution becomes likely, and the world's so interconnected now that foreign powers will take advantage of the malleability of a society undergoing revolution, likely to the detriment of the locals.)
