Hmm. On one hand, I suppose all of these could in fact lead to pain. Likely to, even. As Lucretius points out, these vices “tear a man in two” and “trouble his life”, and he laments about “how many disasters they deal”. To me, this points towards him illustrating how these vices lead to material pain, not any kind of abstract moral failing.
At the same time though, I see your concern Kalosyni - I agree that we ought to be careful about abstract virtues and vices detached from the pursuit of pleasure and the avoidance of pain.
I suppose it could simply be a matter of Lucretius being a product of his time, in the same way that Epicurus wrote from a perspective of gods existing (though not interfering of course).
It could also be Lucretius being Lucretius. From what I’ve seen, he’s rather flowery and dramatic with his language, and seems to use language in a way intended to elicit emotions, even if it takes away from precision.
