Seneca · On the proper time to slip the cable
Letters 70.28
Reason, too, advises us to die, if we may, according to our taste; if this cannot be, she advises us to die according to our ability, and to seize upon whatever means shall offer itself for doing violence to ourselves. It is criminal to “live by robbery"; but, on the other hand, it is most noble to “die by robbery.” Farewell.
Seneca, Letters to Lucilius 70.28, translated by Richard Mott Gummere
