Robin Hood almost certainly didn't exist, and we need a lot more information to provide any kind of historical explanation of his morality- do you mean relative to the period in which his story was told? Which period?

Apoloigies, but I am forced to remove this question.

Our subreddit rules ban "poll type" questions. Your question clearly is meant to poll attitudes of readers about Robin Hoods morals.

You are free to try and rework the question, and resubmit it. A question asking "how have public perceptions of the morality of Robin Hood changed from the creation of the tale to present" (for example) would not be a poll type question, and would lend itself to sources rather than opinion.
