I think 343 guilty spark is from a conversation in halo ce’s making
343: I want to take over
bunji: we barly started, we will delay in to our 4th game
343: than no deal! Good luck!
bunji: ok, ok, we’ll make a character called 343 guilty spark, it will die in halo 3
343: DEAL!

I think it says that 343i wants to take over halo, but bungie wanted to delay until game 4. However, 343 said no and bungie satisfied them by creating spark and killing him off in h3. Of course it’s entirely incorrect.
Actually if you go by lore, Spark isn’t dead. It remembered its life before it became a monitor, and hijacked a UNSC ship to try and find the librarian.
