The Third Tetralogy: Prosecution for Murder Of One Who Pleads That He Was Acting in Self-Defence (4.3-4.7)

As the presumption supports us as much as it does the dead man, the balance is in our favor; for according to the witnesses, it was he who was the aggressor. This being so, the defendant is cleared of all the other charges brought against him as well. For once it is argued that, because it was only the blow given by the striker which obliged you to seek medical attention at all, the murderer is the striker rather than the person immediately responsible for the man’s death,[*] it follows that the murderer was he who struck the very first blow of all: because it was he who compelled both his adversary to strike back in self-defense and the victim struck to go to the physician. It would be outrageous, were the defendant, who was neither slayer nor aggressor, to be held a murderer in place of the true slayer and the true aggressor.

Nor again is the intention to kill to be attributed to the accused rather than to his accuser. If it had been the case that, whereas he who struck the first blow had meant not to kill, but to strike, he who was defending himself had meant to kill, then it would have been this last who was guilty of the intention to kill. As it was, he who was defending himself likewise intended to strike, not to kill; but he committed an error, and struck where he did not mean to strike.

He was thus admittedly the wilful author of the blow; how can he have killed willfully,when he struck otherwise than he intended?

Further, it is with the aggressor rather than with him who was defending himself that the responsibility for the error itself rests. The one was seeking to retaliate for the blows which he was receiving, when he committed his error: he was being forced to act by his attacker; whereas with the other, it was his own lack of self-control which caused him to give and receive the blows which he did: and so, since he is responsible both for his own error and for his victim’s, he deserves the name of murderer.

Again, his defense was not more vigorous than the attack made upon him, but much less so: as I will show. The one was truculent, drunken, and violent; he took the offensive throughout, and was never on the defensive at all. The other was seeking to avoid blows and repel him; the blows which he received, he received from no choice of his own and the blows which he gave were given in defense of himself against the aggressor, and much less vigorously than that aggressor deserved, because his only object was to avoid the hurt which was being done to him; he did not take the offensive at all.

Even supposing that his defense was more vigorous than the attack made upon him, because there was more vigor in his hands, you cannot justly condemn him. Heavy penalties are invariably provided for the aggressor: whereas no penalty is ever prescribed for him who defends himself.
