In Batman: Crimson Mist- the third part of the trilogy that began with Batman & Dracula: Red Rain-, the now-vampiric Batman, having surrendered to his new dark instincts, kills Black Mask and the False Facers, leaving the gang's severed heads impaled on the spikes of the fence around Blackgate, the faces looking in to the prisoners in an action interpreted as a 'warning'. Batman later reflects, when contemplating his rapidly depleting supply of 'deserving' prey- attempting to kill only those who are themselves killers- that many of Blackgate's inmates are only in for theft or less, grimly musing that they do not deserve his kind of death.
