If this is the case, then what hold should morality(even relative) have in the day-to-day existence? Should not everything break down into hedonistic impulse/instinct lifestyle?
None - lets go rob some banks with explosives!
Some - it keeps us (relatively) safer, therby prolonging existance.
Lots - The flow of the system depends on the invisible bonds! Snap them and it will all come tumbling down!
Some other option other than above.
Defend your answers, cuz you know I'm gonna be following up on this one.
