Rant incoming
Thanks for the cool thoughts. I have always thought that greed was the base of all the other sins but wrath or something. Now i can see the contextual difference. So his shtick is pure desire... hard to comprehend honestly.
Well, it depends a little on how you interpret the seven deadly sins and what you use as your frame of reference, if it's like Bible or some other religious texts, you could probably argue all sins have the same base, but they're reflected in different ways.
If you try take a more wide interpretation of sins, I would argue they're all based on desire and pleasure as a whole, but taken to a level that overwhelm everything else, even to the detriment of the person well-being.
I say desire and pleasure because they probably walk hand-in-hand when it comes to the seven deadly sins, you don't just desire something, but also take pleasure from it, indulgently, overwhelmingly, you wallow on it even if it is something you know is completely negative.
In order of increasing severity.
Lust (Luxuria) - intense and unbridled desire for something, sexually is the most common form, but it can be anything, money, power, knowledge, it's not necessarily about owning or even consuming it, you simply
want it above all else.
Gluttony (Gula) - intensive desire to consume something, overindulge on it, overconsume to the point of being wasteful, food is the most common form, but it can have other forms, like videogames, watching sports, compulsive purchasing, anything you can overindulge in its consumption.
Greed (Avaritia) - intense desire to own something, normally it's about riches, money, jewels, gold, anything with monetary value, but it can be anything you consider valuable enough to own, the point of greed is that
you own it, it's
yours, whatever you get from Lust and Greed can be shared, but Greed is selfish, it's all yours and only yours, be it money, power, knowledge, no purpose besides hoarding what you see as valuable.
Sloth (Acedia) - probably the sin with the widest scope, you could even interpret it as a lack of desire, in it's most basic form you can see it as just laziness taken too far, but it can be emotionally, socially, intellectually, socially, with spiritually being its worst form, you simply want to avoid any hard work, any commitment, you revel in the fact that you can take the easy way of things while others do it the hard way,or you don't really care, you desire to do bare minimum possible in whatever aspect you choose or avoid having to do certain things even when you know you should.
Wrath (Ira) - intense or even uncontrollable feelings of anger, rage or hatred, to the point of revenge or even directing it at the innocent, the thing with Wrath is that it goes to the point where you desire harm to the person, it goes beyond any reasonable thought, you simply can't control it, take pleasure of the idea of seeing the person suffering, but it can also be at things, at concepts, feelings, whatever it is, you simply can't accept they exist, their existence in itself is an affront to you, and you desire nothing moe than to see it gone and take pleasure at doing that.
Envy (Invidia) - intensive desire for something someone else has, unlike some people say, jealously is not necessarily negative, because it should make you strive to be better, you're jealous of a car someone bought? You work hard to get it too, Envy meanwhile is spiteful, bitter, angry, you don't just want what the person want, you want them to lose what they have, as usual material is the most common form, but it can be anything, a good family, beauty, health, having what they have isn't enough, they need to suffer for daring to have what you wanted.
Pride (Superbia) - the original worst of all, the mother of all sins, inflated self steem and narcissism is its most common form, but it can be for other things, you have the best car, the biggest house, the most beautiful wife, the smartest children, it's not enough that you know you're better, you desire to be acknowledged as better, you take pleasure in knowing nobody can ever get at your level, nobody can prove you're wrong.
Vanity (Vanagloria) was originally a separate sin, but it was merged with Pride since they're too similar, and if you go by some religion sects, Despair (Tristitia) is the eighth and actual worst deadly sin, it's not just about feeling despair, you completely embrace it, you reject any and all hope, completely stop trying to strive to be better in any way, some could see it as the logical extreme of Sloth and the opposite of Pride, but one big thing about Despair as a sin is that by rejecting any hope you're also rejecting God, unlike the other deadly sins which you can arguably take by themselves without religious context, Despair is explicitly connected to abandoning hope and salvation in God, it's the only unforgivable sin, supposedly Despair is the actual reason why some see suicide as a sin, it's not due to suicide in itself, but because you completely gave up on believing in hope and in being saved by God.
I would argue against Despair being a sin due to the religious nature, all other form of sins are related to a form of desire, of seeking pleasure, you actively seek them, turn it into a form of hedonism, while for someome to truly fall into Depair it would be so divorced from desire and pleasure as to be completely alien to the other sins.
