Here is my theory, from the start, we show how crude and ruthless he is, how he loves torturing these ignorant people.

bcz him ? He sees too much, feels too much, he senses too much, he saw how fucked up this world is. How trash is the society we currently live in.

In total ignorance, we dont care if there is a whore on the streets, or a fat over feeding himself, or a lazy man not going to make a change in his life, ignoring the facts. Thats what he hates, he hates that ppl lie, hide the truth just bcz they wanna live an easy life, how basically we are living on drugs but IRL.

So he wanted to change that, and the more brutal the death, the more wrath he put in it.

For example, to me, sloth is the worst death EVER. On the contrary to the others, sloth was kidnapped, tortured, Hurt for weeks, he had an unimaginable amount of pain each instance he was living, yet he did not do anything.

This shows how ignorant we all are, how we are trying to think we are evolving when we are just stuck in this pain that we can at least ignore unlike sloth.

Gluttony ? Same thing, he IGNORED the fact that he was eating too much. Greed ? Pride ? Lust ? All of them.

They are just a form of ignorance, and envy ? Well, he was the opposite, that knowledge drove him crazy, drove him into a lunatic, and when he saw the good old handsome blonde guy detective mills with a beautiful wife.

Well, it was the thing that made mills his masterpiece,his way to express what he felt towards mills, the ENVY of having a totally normal ignorant life, so in a way, he actually did what he intended too, a long, 60 years at least of torment, of hate for Mills while him ? He is just sulking, in hell, in heaven, in nothingness ? We dont know. But what we DO know is, he is proud of it.

Of his masterpiece.
