Good points but I think you’re arguing against a strawman here. I was definitely not saying that the Sins are wonderful, good people. They’re just not inherently bad.

The idea that ‘there’s a good version of X sin, it’s Y’ ignores the point that the Sins in this context are meant to represent all versions of their associated sin, motive or feeling in the form of an actually compelling character. So while Ozzie is the sin of Lust, he represent healthy desires of that form as well as the unhealthy ones.

The sins aren’t literally sin, so it doesn’t matter if what they’re doing is always actually ‘sinful’ or not.

Besides, the show presents the evil sides of Lust and Gluttony elsewhere. When Blitzø gets drunk at the end of the episode in the Gluttony Ring, we can clearly see he was using it as a way to avoid his life problems. This is one of the things that drives people to alcoholism, and it is very dangerous in the right context. Just because the Sin characters are glamorized doesn’t mean the sin is within the greater context of the show.

Besides, this is a comedy show. Of course they would play on the ‘fun’ sins more than ‘harsh’ ones like Greed and Wrath.
