Why is justice supposed to be blind?
Justice is supposed to be blind because it is not supposed to have any personal bias. When a judge looks at a small-framed woman who supposedly committed murder he must not feel sympathy for her due to her size. Her lawyer may use her small frame as an argument if the victim was strangled or something, but the judge should only be looking at the facts of the case, he or she should be blind.
The actual concept of this blindness came from ancient Egypt, who agreed that courtroom theatrics, or the look of a defendant or plaintiff, could influence a judge. The solution was to hold their trials in darkened chambers, with absolutely no light. This concept inspired the well-known statue, Lady Justice, of a blindfolded woman holding the scales of justice
