He did everything he could: he trusted her, supported her, and helped her constantly, no matter what the problem was. Lightning on the other hand didn't, therefore the anger, the blame, and the guilt. This also leads to the punching scene in Chapter 3, where Lightning simply couldn't take anymore of that “I'll protect Serah” bullcrap that Snow kept throwing at her all the time.
