Socrates was asked by Perdiccas why he wouldn't come to him. Socrates said, "So I won't die the worst kind of death — unable to repay the good that has been done for me."
What Socrates answered unto Perdiccas, why he did not come unto him, Lest of all deaths I should die the worst kind of death, said he: that is, not able to requite the good that hath been done unto me.
