Let us kill these robbers.
Caveant intemperantiam, meminerint verēcundiae. (Off. 1.122)

Note 2— The term Hortatory Subjunctive is sometimes restricted to the first person plural, the 2nd and 3rd persons being designated as the Jussive Subjunctive; but the constructions are substantially identical.
Note 3— Once in Cicero and occasionally in the poets and later writers the negative with the Hortatory Subjunctive is nōn
Ā lēgibus nōn recēdāmus. (Clu. 155)
Let us not abandon the laws.
a. The 2nd person of the Hortatory Subjunctive is used only of an indefinite subject, except in prohibitions, in early Latin, and in poetry.
Iniūriās fortūnae, quās ferre nequeās, dēfugiendō relinquās. (Tusc. 5.118)
The wrongs of fortune, which you cannot bear, leave behind by flight.

For negative commands (Prohibitions), see § 450.
b. The imperfect and pluperfect of the Hortatory Subjunctive denote an unfulfilled obligation in past time.

Nē poposcissēs. (Att. 2.1.3)

Saltem aliquid dē pondere dētrāxisset (Fin. 4.57)
At least he should have taken something from the weight.
Note 1— In this construction the pluperfect usually differs from the Imperfect only in more clearly representing the time for action as momentary or as past.
Note 2— This use of the subjunctive is carefully to be distinguished from the potential use (§ 446). The difference is indicated by the translation, should or ought (not would or might).

Note— The Concessive Subjunctive with quamvīs and licet is originally hortatory (§ 527.a-b).
