HE LOVES NOTHING.
In order to love, there is fear attached in the possibility that it may be lost.
If a man fears nothing, this means that he has nothing that he holds close to him. If he held something close to him, he would be terrified of losing it.
A man who may come across as someone who fears nothing - may interestingly just be the man to fear everything.
To never have, is to never lose. No risks.
What kind of life is that?
