Yet he had great faults. He was far from being so pure and so venerable as Eusebius, blinded by his favor to the church, depicts him, in his bombastic and almost dishonestly eulogistic biography, with the evident intention of setting him up as a model for all future Christian princes. It must, with all regret, be conceded, that his progress in the knowledge of Christianity was not a progress in the practice of its virtues. His love of display and his prodigality, his suspiciousness and his despotism, increased with his power. The very brightest period of his reign is stained with gross crimes, which even the spirit of the age and the policy of an absolute monarch cannot excuse. After having reached, upon the bloody path of war, the goal of his ambition, the sole possession of the empire, yea, in the very year in which he summoned the great council of Nicaea, he ordered the execution of his conquered rival and brother-in-law, Licinius, in breach of a solemn promise of mercy (324). Not satisfied with this, he caused soon afterward, from political suspicion, the death of the young Licinius, his nephew, a boy of hardly eleven years. But the worst of all is the murder of his eldest son, Crispus, in 326, who had incurred suspicion of political conspiracy, and of adulterous and incestuous purposes toward his stepmother Fausta, but is generally regarded as innocent. This domestic and political tragedy emerged from a vortex of mutual suspicion and rivalry, and calls to mind the conduct of Philip II. toward Don Carlos, of Peter the Great toward his son Alexis, and of Soliman the Great toward his son Mustapha. Later authors assert, though gratuitously, that the emperor, like David, bitterly repented of this sin. He has been frequently charged besides, though it would seem altogether unjustly, with the death of his second wife Fausta (326?), who, after twenty years of happy wedlock, is said to have been convicted of slandering her stepson Crispus, and of adultery with a slave or one of the imperial guards, and then to have been suffocated in the vapor of an overheated bath. But the accounts of the cause and manner of her death are so late and discordant as to make Constantine's part in it at least very doubtful.
