The first sentence is present tense. The other three are future tense.Originally Posted by jack
The tense of a sentence depends on the main verb. In all four sentences "killed" is the past participle of the verb "kill". In all four sentences, this participle is used to form the passive voice. This is formed by [from of "to be"] + past participle. "Get" is used to replace the "to be" form (informal use).
The active voice infinitive of "kill" is "to kill".
The passive voice infinitve of "kill" is "to be killed" (to get killed).
He gets killed (he is killed). [present tense, passive voice]
He got killed (he was killed). [past tense, passive voice]
He will get killed (he will be killed). [future tense, passive voice]
