“Hence there arose very early a difference, still deeply rooted in the law of negligence, between ‘misfeasance’ and ‘nonfeasance’ — that is to say, between active misconduct working positive injury to others and passive inaction or a failure to take steps to protect them from harm.” W. Page Keeton et al., Prosser and Keeton on the Law of Torts § 56, at 374 (5th ed. 1984).
