for killing 9 flies will I be given a war crimes trial?

Maybe not, but you will have to spend your next 10,000 lives as a fly and get squished every time.

Only for spiders

They will have to prove you did it and that they didn't die from natural causes. Did you dispose of the bodies?

🤣 i am certain you will so if convicted you will be looking at serious jail time [taters]
