Morality is an external system of principles that vary upon culture. In the end, we either turn to these or we turn to within, often to feel better about ourselves. But often, even those lines can seem to blur. I do not believe there is a universal right or wrong, but I do believe that in having values we have control and do not operate on mere instinct so in a way it is like mastering oneself, a degree of self control and awareness.
So I still value it's importance as long it follows that actions weak or petty seeming or without meaning, like if someone has there back turned in a fight, you don't hit them from behind and then rub it in that you won. You cheated, and that in itself is weak and proves nothing of your own strength and is thus dishonorable. Or like on murder mysteries all the people killing other people over jealousy which is nonsensical, enforcing the whole "If I can't have him no one can" childish pure negative emotional based behavior, loss of self control. I have a logical basis for self-control. These all lack logical basis and show lack of control, which is the core of what my values would be against.
I have essentially built my own structure off logic and self-control basically. A balance, of the two. But have nothing to do with societies values.
