Well I mean, this just suddenly became weirdly chaotic. I don't really find MC's actions justified. The "I read in the diary" thing seemed to be some very last-minute stopgap measure. And "offerring the tree" seemed neither necessary nor urgent, so like, it's a big "wtf?" for me. And while I have mixed feelings about the "killed" participants in the world tree, it didn't seem necessary to antagonize Solia.
