you only have control over your own actions. nothing anyone could ever do or say to you can force you to act. you decide. morality is morality. it's defined by what you believe is right, which most often is defined by what makes you happy. Morality is often imposed by a collection of people (a culture) who have come to a general consensus on the way they want to treat each other, which is based on how they want to be treated. we all die eventually. outside of a belief in a meta-physical (spiritual, after-life, reincarnation, etc.) there's no purpose to anything in life because it's all just a cosmic accident and you only exist on accident. you will die, everyone you know or ever will know will die. No matter your legacy, all will return to dust and nothingness. there's no purpose. That is, assuming there is nothing more than what is physical.
