Should we feel sorry for Esau for losing the blessing?

Les explains that Esau got shook up when he was more or less robbed of the blessing, but he didn't care about the spiritual or the birthright. The blessing meant the double portion of herds and flocks, and that was what he hated losing. Paul calls him a fornicator and a profane person; he was destitute of faith and immoral. He sold his birthright for one morsel of food. When he later would have inherited the blessing, about 37 years later, he was rejected by God and his parents; he found no place of repentance though he sought it carefully with tears. Les does not think Esau sought his own repentance, since he had no faith and did not believe what God said. Rather, Esau tried to get Isaac to change his mind after Isaac had blessed Jacob, but under the law of the ancients, when it was spoken it was done. Isaac could not reverse the decree, and Esau deserved neither birthright nor blessing because he had no faith. He was not cheated or rooked; he was immoral, as shown by marrying among the Hittites and Canaanites.
