If there are intrinsic, objective values, then we have something to guide our lives and decisions by.
Is there some intrinsic value to "Love"? If not, then why should love be your measuring stick? If a narcissist loves himself and knows no shame, can he do no wrong?
Why would it matter that we love ourselves? Or anyone? Especially if there is no objective right or wrong...
the problem is that there is nothing concrete to follow, unless you ascribe to a religion or a doctrine. there IS nothing intrinsic by which to measure things.
ultimately, the ONLY person that any of this matters to is ourselves. we can say all day long that it matters to other people, but it is impossible to really
know anything about what others feel or think.
we will never be able to think a thought with or for another person, nor will we ever be able to feel a feeling with or for another person.
we truly are alone in our unique experiences. so, ultimately, the only person we CAN live for is ourselves. the objective right or wrong is ultimately determined by the individual.
morality really has nothing to do with everyone else, but everything to do with us. either we live a life we are proud of and love, or we live a life we are ashamed of and regret.
speaking as someone who actually was diagnosed as a sociopath, i can tell you that they are asleep. to them, they do no wrong. no moral system will convince them otherwise. to them, all of their actions are moral. but, i can also tell you that they do NOT love themselves.
back then, i used to tell myself all kinds of things to convince myself that i was above everyone else. that i was somehow better. but, i did not really love myself. if i had, i would have been happy. instead, i was just existing, constantly looking for my next exploit that would tell me that i was better. shame was an emotion that i actively fled from at every turn.
so, yea, they know what morality is. but they refuse to accept it. the only measure of morality is the self. and those who do not love themselves are not moral. simple as that.
i hated myself back then. i can admit that now. i despised people because i hated myself. nothing i did was every good enough to convince me otherwise. i always needed more, it was never enough.
from what i can tell, most people refuse to see themselves as an entity they have complete control over. since they dont see themselves as entities completely within their control, they have to find ways to justify their actions and thoughts. and hence, they struggle with morality. they cannot even define it.
so yes, i would say the only measure of morality is love. if you make a mistake while trying to love yourself and those around you as yourself, you have not done anything immoral. you have simply fallen victim of ignorance. if you want to never fall victim to ignorance, then you must be aware.
none of us are fully aware of anything. we are all bound to make mistakes. we can still be moral though, should we decide to be. even with the mistakes.
