If morality is subjective...

[Mudhammam]

When theists argue for God's literal, objective existence, they appeal to logical axioms that are considered necessarily true due to their structure. A similar process of reasoning is utilized when formulating ethical statements to be considered true or false. An ethical maxim such as the Golden Rule or its reverse ("thou shalt not do unto others...") is derived from an axiom such as "X is bad" where "bad" is defined, perhaps with more difficulty, by physical interactions that inflict pain or displeasure, though these are also blanket terms; we often realize there may be certain forms of pain or situations of displeasure where their presence is tolerated or even considered "good" in relation to the ends they serve. There may be no objective definition of "bad" but there are objective facts about reality that contribute to pain and displeasure in a sense that careful reasoning can disintegrate into notions of "bad" or "evil" found agreeable by most individuals within and across different cultures.
