I do appreciate Nietzsche, but I don't believe morality can be interpreted objectively. Tried to interpret from an objective stance, morality ceases to exist for me. I don't necessarily agree with putting morality into two subsets, such as "slave" and "master", as I believe it is much more complex. Not to say I think Nietzsche was wrong in categorizing it in such a way, I think he was doing his best at objectively categorizing something that doesn't exist outside of subjective interpretation.

I try not to look at morality past the point of what comes naturally. Other peoples emotions are just as important as mine, whether I'm experiencing them or not, and innately knowing this allows me to feel someone else's emotions to a certain extent. If I feel bad, I'll do what I can to correct this feeling. If I can make someone else feel good, and in effect, make myself feel good, I will do my best to make that happen. Now where it gets tricky is when I do something that makes me feel pain, to make something else feel better because I know it's the right thing to do. Or from the other side, when I do something that hurts something else, to make myself feel pleasure, even though I know it's the wrong thing to do. I've realized that when reflecting on the good things I've done despite negative emotions it may have caused me, I can feel good about those things for the rest of my life. While the bad things of done for pleasure, lead me to feel shameful and bad about myself. I don't consciously think about this every time I make a decision, but I believe it's an underlying force that helps to drive my actions.

Now obviously this is all very over-simplified. There are actions that I would consider the right ones to take, even though they may cause yourself and others pain, for the greater good. This is where I think morality gets very tricky, and what I think Nietzsche meant by his "master" category. But it is still intertwined with his "slave" category of morality.

I realize all of this probably seems very obvious, and I don't mean to sound patronizing, I'm just sort of writing as I'm thinking, unfiltered. I hope my rambling was somewhat thought provoking.
