Does moral nihilism oft lead to same conclusions as morality?

I believe that there is no inherent morality meaning that there is no definite right or wrong, good or evil. It is all subjective. This doesn't mean that I don't have morals though. It just means that the morals I have are completely made up based on my likes and dislikes. I don't think that murder is inherently worse than donating to charity, but I would rather witness a donation than a murder. I think everybody has morals whether they think they do or not because they are founded on instinct. Basic moral principles are founded on what humans like. Do not steal because people do not like their things stolen. Do not murder because people do not like to die. Do not lie because people don't like being lied to etc.
