I think this is more like a natural fear for our favorite route character to be the culprit. It also happens to me, I get overly sensitive to the things my fave one says and does and I'm like please, don't let him be the one who is doing all this at the end, even if maybe there is a chance there is a not so evil motive for all this (Like starting all these cycles so at the end they find one with a miracle or low probability scenario... or maybe I should just stop watching Higurashi before reading the novel)
