Yea i would say they would mention if they ate their dead...etc. Their are many remnants of, i read in other thread, Taoism influence. Whether true or not is just another debate. I dont know anything about Taoism and Hinduism enough to identify it in the game, but cetainly other people have.

When squall and party walk through the dead white seeds before entering ultys, they comment on the seeds fighting across generations and...walk right around them to the final stage. Would a funeral service been optimal at this point? They had a job to do, to avoid more deaths, and "slavery for eternity."

They are caught up in the war moment. Funerals didnt happen in vietnam in the battle field in the 70s. Yes they were brought home and acknowledged, burried...etc. but not at vietnam, (where the story is taking place). If anyone began to mourn, theyd be killed themselves. The FF world was a battle field.

These seeds are trained to kill. Mourning is left for civilians during the battle. When it is all over, then yes, this is where they could have had some sort of funeral to acknowledge the dead. It would have taken place after the celebration though...after the game ends. Basically it did with SPOILER Raines Grave, but it had nothing do do with battle, it was part of the plot (Raine being squalls mother)

But simply, it isnt part of the story. And it can be hated for that. The creators are trying to capture real combat mentality, when all that matters is you and your squad staying alive to finish the task, nothing else. Its a conflict between civilians at home and soldiers in combat. They dont see things eye to eye (like shooting children-soldiers can be seen as wrong to some and "thank god he didnt shoot me first" to others)

Second, (forgot) And taking time to talk to Edea, part of the plot of Squall and Rinoa. Rinoa is his first thing close to livlihood, his motivation to continue fighting.
