Sometimes being rebellious is a good quality, while most of the time it is not. It is good to think different from the others, but the motive should not be to stand differentiated.

A rebel tries to do different things, to appear unique!
  
A rebel is someone who goes against the majority. They may be right or wrong but are subject to criticism because they do not follow the crowd. Being a rebel has its own advantages as well as disadvantages.
 
Advantages
Disadvantages
Individual thinking is encouraged instead of following what everybody else does.Involves a lot of research and study, to prove a point wrong and establish our thoughts.
A different perspective is obtained when we think different.Should be welcome to criticism, even if he is right.
If his thoughts are right and justified, it can become the new norm.The motive should not be to stand unique from the rest. The motive should be to prove our thoughts are better than those of others.
