Why don't Survivors ever blame each other for their mistakes?
When a survivor sandbags another, it's the killers fault for going through with it. When a survivor unhooks somebody near the killer, then sprint bursts/lithe/balanced landing out of there, the killer is apparently tunneling. When a survivor runs laps with the killer around a hooked survivor, or circling the area knowing the ultra altruistic survivors are right there, the killer is camping. There are other instances of this, but these are the ones I see most often.
My point is, it bugs me how the killer, seen through numerous 'camping, tunneling, slugging, toxic, etc' posts, is pointed out as being the 'bad' player, when in a lot of situations, their teammates are to blame for what happens. So, why is it the case that survivors generally ignore the mistakes/blatant farming of their teammates, and instead place all the blame squarely at the killers feet?
