Why would god brand a sinner with a mark that is tiny and easy to hide as opposed to one that is a clear and obvious and hard to conceal?

As for lust, I do not quite understand what you consider a theme for lust. Lust, as I understand it, is a powerful, visceral and carnal desire, an intense want for something, a passion that is unwholesome and perverse in its strength and is capable of driving a man to unspeakable acts in pursuit of fulfillment.

My guy, as i have already explained previously, currently embodies and expresses lust by being self-centered and egoistical and narcissistic to the extreme. Everything he does, he ultimately does for his personal fulfillment and pleasure. He can never force himself to extend more than a simple token effort to help someone else in a meaningful way if it is in any way difficult or hard, but he will go to any lengths to make himself feel good, or to chase an object of his passion - it's just that due to his history and memories being shrouded he is yet to remember the sheer perversity and depravity he can be capable of, and so for now his lust is mostly internalized and expressed heavily in being a self-centered bastard that thinks he is a nice person but is too hypocritical to admit that in reality he cares only about the praise he receives and not about whatever goodness he does. If and when something in his situation changes, if he begins to hunger for something greater and more intense, his true and utterly villainous colours would show.

But if lust here is supposed to be purely some sort of carnal lecherous desire for material wealth and sexual conquest i can do that too.
