They should get manslaughter, right?

I know this case is somewhat cursed and that we don't want to wish for too much but isn't manslaughter what they should have gotten? Their case had sooo many witnesses and proof of their claims. If they were convicted today it would surely be manslaughter right? I don't want to get my hopes too high either but it's just so insane to me that they got such a harsh sentence. It feels like there's corrupted powers at play because nothing about this case and outcome makes sense. We should be able to wish for manslaughter without it sounding so crazy to others but since this case seem to be unfairly cursed and biased when it comes to the media I understand why we are all scared. I guess all we can do is pray and dare to have a positive mindset🙏🏻
