Arguably no one deserves to be hunted down and killed by some psycho in a costume but who are some of the most innocent victims in ANY slasher? Even when we get a revenge slasher, there are random innocent people that weren't involved that are killed to add to the body count.
My go to answer is everyone in the first 'Friday the 13th' (1980). Pamela wanting to kill them is a mixture of her wanting to do something severe so the camp finally closes down forever and her just having snapped after her son died. Her anger leads to psychosis and makes her believe these counselors killed her son even though they all either weren't born or were very little when Jason drowned. She also spends the entire movie watching them be responsible and seem like they take their job very seriously.
Annie tells Pamela how much she loves kids and how it's been her dream forever, everyone rushes to Ned's side when he's "drowning". Two of them jump in the water, one gets in a canoe and paddles out to him, one throws a life preserver out to him and then one gives him CPR. Yes Ned was playing a prank and that upset Pamela, but everyone proves themselves to be very responsible. When Pamela is pretending to be a little boy in danger, Brenda runs out to help in the middle of the night barefoot with nothing on but her nighty, into the freezing pissing rain to help this scared lost child she can't even see. All of them are great people and the exact people you want taking care of kids.
Don't matter though. You guys are responsible for Jason dying or at the very least, are just used to be the thing that finally gets this camp shut down forever. Nothing but bodies, could of been anyone. Dark, tragic, and sad.
