Doctor uses Davros's life support as threat

Trapped in the interrogation room with Davros, the Doctor abandons appeals to morality and instead weaponizes Davros's vulnerability. Wrestling the scientist’s arm, he accesses the switch controlling Davros’s life support and threatens to disable it permanently unless Davros orders the destruction of the incubation chambers. Davros, horrified by the prospect of death, issues the command—but Nyder intervenes, coshing the Doctor and restoring Davros’s command over the situation. The Doctor’s desperate gamble exposes the fragile limits of his ethics when faced with total destruction, while Davros’s immediate reversal underscores his ruthlessness in prioritizing his project above all else.
