okay opinion time, as we all know this'll be about claudandus like always, and this time, its OpInIoN time. claudandus honestly didn't deserve to die, and here is the reason i think this way. firstly his backstory, they show it a few scenes before francis finds out that 'pascal' was claudandus, when the tape played. It showed claudandus was obviously being tormented and treated horribly, which kind of gives him reason to be the way he was at the point where francis found out his true identity But still, killing cats was wrong, but as i say a lot of times, he had perfectly valid reasoning behind it. Yet francis was too naive to understand, so, like the dickhead he was, he decided to kill claudandus for things he did in the past like dude, HE WAS FORCED TO KILL, WHY WOULD YOU DO THAT. and on top of that, claudandus had stomach cancer (probably due to the experiments, but this was never explained). So that makes you look like more of the bad guy.
