根据Gottfredson与Hirschi在1990年出版的书籍《A general theory of Crime》所写,人的所有行为皆能理解为追寻自己的愉悦或避免痛楚(All human conduct can be understood as the self-interested pursuit of pleasure or the avoidance of pain.)。
Re 16楼:那是极端状况。引用法的概念,也是有顾及到这点的,然而在那情况下,必得有医学证明该病者「没救」
Re 17楼:无疑,道德伦理存在于约定俗成。它规范了人要负责任,如中庸说的:「故君子以人治人,改而止。忠恕違道不遠,施諸己而不愿,亦勿施於人。」,又如Jones and Cristie在《Criminal Law》一书中所举的一个例:「A person who supplies potentially dangerous drugs to a victim, in the knowledge that the latter intends to consume them, is responsible for the harm suffered.」(1995 SLT 248; 2000 SLT 771; [2007]UKHL 38) 如果是没错的,又何须负责呢?(对应Jones and Christie)所谓己所不欲勿施于人(对应中庸),如果是大家都不想承受的,那就应当是错的,就如Gottferdson与Hirschi在A general theory of crime一书的说法一样,人皆不欲痛,所以「水中照臉、彼此相符。人與人、心也相對。」(和合本箴言,27:19)
