This name hasn't always been used ambivalently but it has been used as a way to protect the child from death by giving it the name like this so that death will overlook the child or act as a fright for evil spirits - hence it is a way to overcome death. Many Slavic names have been used as good luck charms but many people don't realise, even those of Slavic heritage.

Also I forgot to mention that the name in pre-Christian era, a name of a god or goddess was given as a way to pay respects to and honour the god or goddess who will act as a protector/guardian, in this case Morana, and thus this name is used in order for Morana to be lenient towards the child and thus spare the child from death. This name was thus used as a way for a child to escape death with the explanations as to how to do so mentioned here and in the post above.
