I think the exact logical flaw is that saying "slowing down development for testing costs lives" assumes the solution will be validated as correct. Waiting a year to deploy the correct solution for want of testing costs the lives that solution could have saved in that year, yes, but pushing one correct and four incorrect solutions immediately into production - when the incorrect solutions each cost twice as many lives as could have otherwise been saved - and re-evaluating after a year kills far more people than are saved.
