Non violence is different from peace. Peace is a term that has an extremely broad scope and can relate to many different concepts including tranquility, lack of activity, absence of violence, etc. Non violence has a more narrow definition and refers to the refusal to use physical aggression or threats.
Non violence is an essential choice to make in today's modernized world, not only for the welling being of others, but for the well being of yourself. Choosing peace over violence makes you safer by helping keep you out of violent situations.
To prove that peace over violence is more essential to your well being and even the well being of the world's greatest fighter, you can compare the number of deaths dealt to the winning side of the Indian revolution which used non violent forms of persuasion with the larger number of deaths in modern wars spread across the same time period.
Although, to be fair, there were some moments of violence in the movement on both sides:
The first Non cooperation movement lead by Gandhi in India urged people to boycott British educational institutions and law courts; resign from government employment; refuse to pay taxes; and forsake British titles and honours. However, Gandhi called off the movement following the Chauri Chaura incident, which saw the death of twenty-two policemen at the hands of an angry mob.
In this instance the mob undermined its own success by resorting to violence which caused the leader to call an end to their tactics.
