Dead meat mission from LCS.
This is easily the worst crime committed by a protagonist. Casa didn't do anything wrong, other than not paying the protection money, again Toni's fault for trying to shame him in order to prove that he's a better man than Casa, just because Casa was wearing a diaper, like ..seriously? Even Toni's mother called him out on this nonsensical act.
Secondly, It was a pre planned murder, not something that seems like a reaction because Casa was either disrespectful to Toni or his mother, unlike in the mission Deconstruction where those workers were disrespectful to Kendl.
In fact, Toni's mom herself finds Casa a better man than Toni, and that his act of taking pictures brought shame to her, unlike in the mission Deconstruction, CJ has no history of giving any troubles to those site workers. Its the opposite actually, the workers are the ones causing troubles and problems for CJ's sister. So, a reaction was needed.
In case of Toni, such a reaction was totally unwarranted simply because someone wasn't paying the protection money, furthermore Casa didn't refuse to pay either.
Lastly, the method used in the mission. Toni attacks Casa and cuts his corpse using an axe
(you can even listen the chopping sound) and then puts his body through the meat grinder. Yuckkkk.
Furthermore, Toni even delivers the meat to the restaurant for others to eat.
I don't know how anyone can be so stone hearted to justify this mission or don't find this act as the worst things a protagonist has done than the mission Deconstruction.
