Texts like the Madhupiṇḍika Sutta (MN 18) and the Kalahavivāda Sutta (Snp 4.11) contain alternative dependent origination chains and explicitly offer them as analysis of how conflict comes about, the famous ‘quarrels and disputes’. I don’t think it’s controversial to say that one of the points of DO is to explain the origin of dukkha in the sense of disputes, but is that made explicit in any sutta which uses the standard DO chain?
Similarly, clinging to the five aggregates is said to be the origin of fixed views which, logically, lead to disputes. And I have the vague memory that this is quite clear in some text but I can’t find it now. I’ve been searching the debates on DO here and it seems this hasn’t been covered. Hoping you can help!
