Defensive? Hardly. That level of hubris is funny.

Martin Luther
When questioned whether the Blessed will not be saddened by seeing their nearest and dearest tortured answers, “Not in the least.”
Gerhard “…the Blessed will see their friends and relations among the damned as often as they like but without the least of compassion.”
Andrew Welwood
(speaks of the saints as being) “overjoyed in beholding the vengeance of God ,” and their beholding of the smoke of the torment of the wicked as “a passing delectation.”
Samuel Hopkins
“This display of the divine character will be most entertaining to all who love God, will give them the highest and most ineffable pleasure. Should the fire of this eternal punishment cease, it would in a great measure obscure the light of heaven, and put an end to a great part of the happiness and glory of the blessed.”
Bishop Newcomb
“The door of mercy will be shut and all bowels of compassion denied, by God, who will laugh at their destruction; by angels and saints, who will rejoice when they see the vengeance' by their fellow-suffer the devil and the damned rejoicing over their misery.” Catechetical Sermons
Tertullian
“At that greatest of all spectacles, that last and eternal judgment how shall I admire, how laugh, how rejoice, how exult, when I behold so many proud monarchs groaning in the lowest abyss of darkness; so many magistrates liquefying in fiercer flames than they ever kindled against the Christians; so many sages philosophers blushing in red-hot fires with their deluded pupils; so many tragedians more tuneful in the expression of their own sufferings; so many dancers tripping more nimbly from anguish then ever before from applause."
“What a spectacle. . .when the world. . .and its many products, shall be consumed in one great flame! How vast a spectacle then bursts upon the eye! What there excites my admiration? What my derision? Which sight gives me joy? As I see. . .illustrious monarchs. . . groaning in the lowest darkness, Philosophers. . .as fire consumes them! Poets trembling before the judgment-seat of. . .Christ! I shall hear the tragedians, louder-voiced in their own calamity; view play-actors. . .in the dissolving flame; behold wrestlers, not in their gymnasia, but tossing in the fiery billows. . .What inquisitor or priest in his munificence will bestow on you the favor of seeing and exulting in such things as these? Yet even now we in a measure have them by faith in the picturings of imagination.” -Tertullian, De Spectaculis
There are a couple of good passages in City of God as well, but are really too long to quote.
