That was a Guy Hamilton beat, though. In all four of his Bond films either the main villain or the henchman survives for one end-of-film confrontation with Bond. Goldfinger. Wint and Kidd. Tee-Hee. Nick Nack. It's just something he did to varying degrees of effect. In my opinion Goldfinger and Tee-Hee worked. Wint and Kidd and Nick Nack less so.
