"Not really". You're using the 'future' reference (Squall and Rinoa) to conclude that whatever happened between Laguna and Julia (past) were created for the greater good. Therefore, it wasn't a sad story. I don't get it.
Laguna and Julia genuinely loved each other, and they wanted to stay with each other but they somehow couldn't... due to some difficulties. This is quite common in real life, actually. Don't see how is this not a 'sad' story.
