Mr. dB said:I refused to answer because I found the question to be extremely uninteresting, judging people on some subjective relative morality scale is absurd. All four characters are flawed. The sherrif is corrupt and accepts sexual favors to circumvent justice. Robin and John are, first of all, thieves who deserve imprisonment under the penal code of their time. Robin was a bastard for rejecting Marian's supposed sacrifice. John was a bastard for taking advantage of the situation and for taking his friend's ex-GF. Marian whored herself out to circumvent justice and thereby contributed to the corruption of a public official.
Ranking them is silly.
I agree totally.
