Nah; nothing is absolutely true - just because nothing can be completely true doesn't mean there aren't levels of truth? So things can be more true than other things.
Killing Millions of people for the fun of it is wrong; doesn't mean its wrong all of the time - because 'for fun' is the situation which defines whether its right or wrong and Killing Millions of people can be right. Which means nothing can be completely and objectively wrong becuase nothing becomes that until it has a situation or a reason.
