The answer is that Yosef's forgiveness addresses only one dimension of the wrong. Each brother must still confront his own conscience and the shame and guilt associated with that confrontation may still cause them to quarrel. The brothers can no longer deny the sale was wrong; Yosef standing in front of them as the viceroy of Egypt proves they did the wrong thing by selling Yosef and deceiving their father about his whereabouts for twenty-two years.
The only psychological escape left is to shrink one's own share of guilt and blame by magnifying the share of others. Rashi articulates his interpretation with precision: "Because of you he was sold. You slandered him and caused us to hate him." The passage’s structure is noteworthy—the speaker, one of the brothers, passively acknowledges involvement ("he was sold," implicating all brothers collectively), while attributing causation to another ("because of you"). He references a prior transgression—slander—and asserts that it led to collective animosity.
The brother effectively states: While he harbored hatred and participated in the sale, he attributes greater culpability to the other, reasoning that his actions were instigated by the other's slander. This shift repositions himself from an active participant to someone influenced or manipulated by his sibling’s conduct.
Within this context, Rashi’s analysis provides meaningful guidance. When an individual claims, "I only did X because you did Y," they shirk full responsibility and avoid candid self-reflection. True integrity requires acknowledging and owning one’s actions without reference to the behavior of others. For individuals who embody integrity, questions such as "Was I as bad as him?" are immaterial; the pertinent inquiry remains, "What did I do, and was it justifiable?"
When Yosef sends his brothers back to Canaan to bring Yaakov to him, he tells the brothers, "Do not quarrel on the way." Rashi explains this in several ways including the following: "According to the simple meaning of the verse, we can say that since they were ashamed, he was concerned that they would perhaps quarrel on the way about his being sold, debating with one another, and saying, 'Because of you he was sold. You slandered him and caused us to hate him.'"
This commentary by Rashi shows a deep awareness of how integrity can be undermined. He suggests that feelings of shame can spark arguments, which then turn into accusations about who is most responsible for the wrongdoing. The brothers had all participated in selling Yosef, but not equally. Some proposed killing him. Some suggested that they throw him into the pit. Some advocated for his sale. Some stayed silent. Each brother knew exactly what he had done and what he had seen others do. Yosef was concerned that each brother may quarrel with the other and say that, “I just remained silent – your actions were much worse, you advised us to kill him,” or another claiming, “Your actions are worse than mine, because you caused me to hate him.”
People react this way because shame is very hard to handle. To cope, our minds try to find relief, often by shifting blame onto others. If I can convince myself that someone else is more to blame, my own guilt feels lighter, even though the actual facts haven't changed—it's just that comparing makes me feel less at fault.
Yosef issues this warning after revealing himself and after forgiving them. One might think forgiveness would eliminate any need for caution. If Yosef holds no resentment, why would the brothers quarrel?
If, as described by Rashi, the brothers engaged in such disputes, their actions would amount to moral arbitrage—attempting to mitigate personal accountability by amplifying the faults of others. However, this strategy is ultimately futile; regardless of comparative blame, each individual's deeds remain unchanged. The spoken slander, harbored resentment, complicity in deception, and collective silence before their father—all represent shared responsibilities that are not lessened by highlighting another's greater fault.
Yosef recognized that authentic repentance necessitates individual self-examination. That is why he advised that each brother must refrain from “quarrel on the way” and not seek solace in comparative guilt or minimizing their actions by referencing another’s provocation. Every individual is called to undertake their unique process of moral reckoning.
A person of true integrity does not evaluate their behavior relative to others nor seek reassurance through others' shortcomings. Instead, they stand accountable before their own conscience, confronting their actions honestly without measuring their conduct against others.
