Is it true that there is no absolute morality?

[Sterben]

 Is it morally good to murder  ?
 Is it morally good to abuse children ?
 Is it morally good to rape ?
 Is it morally good to steal ?
 Is it morally good to have a martial affair?

Nope.  
 

 Knowing it is absolutely wrong to murder can stop an individual from murdering while to say it is arbitrary wrong to murder can justify murder in one's mind

People justify murders even when they do conceptualize murder as absolutely wrong, most of us are morally compromised, though maybe not about murder (lol).  I doubt it's uility, and would point out that it's utility is not a demonstration of it's objectivity...unless you only seek to demonstrate that it's objectively useful, but not necessarrily objectively true.  

Now I'm curious on what the board thinks. If Albert Fishes actions were wrong, and the Romans and Greeks were ok by their standards at the time. Am I a being hypocrite to my own morality?

I don't think so.  Implicit in your assessment of the romans and greeks is that you still consider what they did to be wrong..you simply understand they might not have thought so.  Whereas you can see no circumstance that would diminish the moral culpability of Albert Fish.  You consider both acts wrong, you're differentiating between the actors, not either acts moral status.

         Thank you, ever since I posted this I kept thinking about it and came to a similar conclusion. I was thinking to hard in black and white setting when morality does not have a black and white standard.
