Ah, sorry. I think I understand. How about this: Absalom's curse manifests in form of an nigh-on irresistible longing and [i]want[/i] for corruption and violation of innocent and beautiful things and things that are complete by themselves? To explain - when witnessing a beautiful work of art, such as a painting or a statue that is [i]complete[/i] and beautiful and finished and requires no additions, he would feel a terrible compulsion to somehow hurt and ruin it in a way that'd make it incomplete. Similarly, when witnessing dispalys of purity and spiritual integrity in people, such as helping someone purely out of goodness of your heart, he feels a burning need to make them stop, and make them abandon any pretension of goodness. 

Alternate ideas: First - in a classic biblical Lust fashion, any woman he copulates with will guaranteedly become pregnant and give birth to two or more children who will grow up to become either evil and villainous men, or become destined to confront him later. 

Second - no matter how much he himself takes from the world, no matter what of his own lusts he fulfills, he is cursed to never be complete and whole. No matter how much he eats, he remains emaciated, no matter how kind he is to his men they never trust him completely and never become TRULY dedicated, no matter how lavishly he dresses and how much makeup he applies, there is still a fatal ugly flaw in his apperance, no matter what remedies he seeks the mark on his back still weeps and hurts.
