It is quite evident that their efforts are, in fact, helping many distressed homeowners.

“Literally, their assistance saved my family’s home,” said Robert Robinson, of Felton, Pa., whose interest rate was cut by more than half, making his mortgage affordable again.

But to some, it is disturbing to see former Countrywide executives in the industry again. “It is sort of like the arsonist who sets fire to the house and then buys up the charred remains and resells it,” said Margot Saunders, a lawyer with the National Consumer Law Center, which for years has sought to place limits on what it calls abusive lending practices by Countrywide and other companies.

More than any other major lending institution, Countrywide has become synonymous with the excesses that led to the housing bubble. The firm’s reputation has been so tarnished that Bank of America, which bought it last year at a bargain price, announced that the name and logo of Countrywide, once the biggest mortgage lender in the nation, would soon disappear.

Mr. Kurland acknowledges pushing Countrywide into the type of higher-risk loans that have since, in large numbers, gone into default. But he said that he always insisted that the loans go only to borrowers who could afford to repay them. He also said that Countrywide’s riskiest lending took place after he left the company, in late 2006, after what he said was an internal conflict with Mr. Mozilo and other executives, whom he blames for loosening loan standards.

In retrospect, Mr. Kurland said, he regrets what happened at Countrywide and in the mortgage industry nationwide, but does not believe he deserves blame. “It is horrible what transpired in the industry,” said Mr. Kurland, who has never been subject to any regulatory actions.

But lawsuits against Countrywide raise questions about Mr. Kurland’s portrayal of his role. They accuse him of being at the center of a culture shift at Countrywide that started in 2003, as the company popularized a type of loan that often came with low “teaser” interest rates and that, for some, became unaffordable when the low rate expired.

The lawsuits, including one filed by New York State’s comptroller, say Mr. Kurland was well aware of the risks, and even misled Countrywide’s investors about the precariousness of the company’s portfolio, which grew to $463 billion in loans, from $62 billion, three times faster than the market nationwide, during the final six years of his tenure.
