Doesn't the word "rebel" normally implies a negative nuance? Is it common to call themselves a rebel?

Yes, you're correct in thinking that "rebel" is often used in a negative context. However, "rebellions" are not necessarily bad - you will find many rebellions have taken place throughout history to overturn corrupt or authoritarian governments. If one calls themselves a rebel, it means that they fight for/believe in ideals and principles that may be contrary to the mainstream or what the government promotes. Ex: The rebels are in hiding from the corrupt dictator. Ex: One famous rebellion that changed the course of human history is the French Revolution of 1789.
