Letting the demons in and keeping them out

Since Evelynns reveal we have little insights into the of demons in runeterra but there is still much to learn Firstly let's look a common analogy that the known and speculated demons are compared to: the 7 deadly sins Now if this comparison is accurate in the long run then I'd like to give my 2 cents in how the current demons are categorized. Demons come in all types and each have different restrictions and boundaries so I'd hazard a guess on two classes of demons, TEMPTORS and INFLICTORS

Demons of TEMPTATION LUST, GLUTTONY, GREED, SLOTH are all sins of temptation so before demons of this class can harvest the emotion they need from they're victims they offer these temptations that victims must succumb to willingly tempts with lust to harvest agony tempts with gluttony/ greed to harvest misery The biggest restrictions these demons have is that if their victims do not give into the temptation then they cannot harm them

Demons of INFLICTION PRIDE, WRATH, ENVY are sins that are not offered upfront by are rather brought about by other emotions and actions. These kind of demons are much more dangerous because they can immediately harm you. : it can be speculated that nocturne inflicts great terror upon his victims which eventually leads wrath. it is however unclear if he feeds on the fear or it's a means to an end to another emotion he harvests : I honestly don't know where riot will go with him when his vgu eventually come but if I had to guess , Shaco as a jester attacks the PRIDE of his victims as nobody likes to be the butt of a joke and as his jests get more and more out of control and violent, he either harvests violence or madness

Well that's all I got so hopefully as the lore moves along we get more information on dark mysterious world of demons
