So in the book Oathbringer, it is revealed that the Recreance happened in part due to finding out that this land was rightfully singer (Parsh), but more due to the fear that surgebinders would destroy Roshar, just as they destroyed the Tranquiline Halls - presumably Ashyn, or whatever planet they previously came from. However, why did the Radiants not think that they destroyed that planet due the influence Odium had on their surgebinding? - and I assume in that age they were doing voidbindings instead of surgebindings. They survived millennia on Roshar with their surgebindings as they were under the influence of Honor and Cultivation. Why would they think that they were still somehow going to destroy it? Now back to the 1st point - rightful parsh land. I think it is correctly assumed that this in whole wouldn't and didn't cause the Recreance. Humans generally don't feel remorse over the fact that they are defending invaded land - they do it all the time against other humans (and this is in real life, and on Roshar). Humans are greedy like that, even if they are 'noble' Radiants, as their spren themselves didn't view it in a bad light.
