Lucian Tyrannicida 18

[18] For I was not unaware, man—I was not unaware, nor was anyone else, how much love he had for his son, and that he would not have wanted to outlive him even a little while. To be sure, all fathers no doubt have such feelings toward their children; ‘but in his case there was something more than in the case of others; naturally, for he discerned that it was his son who alone cherished and guarded the tyranny, who alone faced danger in his father’s stead, and gave security to his rule. Consequently I knew that he would lay down his life at once, if not through his love, then at all events through his despair, considering that there was no profit in life now that the security derived from his son had been abolished. I encompassed him, therefore, with all manner of toils at once—his nature, his grief, his despair, his misgivings about the future; I used these allies against him, and forced him to that final decision. He has gone to his death childless, griefstricken, in sorrow and in tears, after mourning but a little while, it is true, yet long enough for a father; gone (and that is most horrible) by his own hand, the most pitiable of deaths, far more bitter than as if it should come about at the hand of another.

[18] I knew—we all knew—his affection for his son; knew that not for one day would he survive his loss. Other fathers may be devoted to their sons: his devotion was something more than theirs. How should it be otherwise? In him, and in him alone, the father saw the zealous guardian of his lawless rule, the champion of his old age, the sole prop of tyranny. If grief did not kill him on the spot, despair, I knew, must do so; there could be no further joy in life for him when his protector was slain. Nature, grief, despair, foreboding, terror,—these were my allies; with these I hemmed him in, and drove him to his last desperate resolve. Know that your oppressor died childless, heartbroken, weeping, groaning in spirit; the time of his mourning was short, but it was a father mourning for his son; he died by his own hand, bitterest, most awful of deaths; that death comes lightly, by comparison, which is dealt by another.
