In my understanding of existentialism, man is meant to live authentically and adhere to his own moral code. Therefore is it justified for a man to kill another or commit some sort of crime because it is what he thinks is right?

The main work of Existentialist ethics is de Beauvoir's *The Ethics of Ambiguity*. She suggests that, no, one ought not to go around being a shithead, which includes not murdering people, because the freedom of others provides the basis for a moral system which rules out (among other things) murder. Sartre (another key Existentialist) agreed with de Beauvoir.
